INA185EVM
1 Overview
The INA185 current-shunt monitor (also called current-sense amplifier) can sense voltage drops across
shunts at common-mode voltages from –0.2 V to +26 V, independent of the supply voltage. Four fixed
gain options are available: 20 V/V, 50 V/V, 100 V/V, and 200 V/V. The INA185 has a reference pin that
enables bidirectional current measurements. The device operates from a single 2.7-V to 5.5-V power
supply, drawing a maximum of 260 μA of supply current per amplifier channel.
The INA185 devices are currently available in a SOT-563 surface-mount package. Table 1 lists the
available gain options.

INA185EVM
2 Hardware
The INA185 is an integrated, op amp-based current sense circuit that provides ease of use and high
performance. The INA185EVM is intended to provide basic functional evaluation of this device family. The
board layout is neither intended to be a model for the target circuit, nor is it laid out for electromagnetic
compatibility (EMC) testing. The INA185EVM consists of one PCB that can be cut into four individual
PCBs segments, one for each of the four device gain options.
2.1 Features
The layout of the INA185EVM printed-circuit board (PCB) is designed to provide the following features:
• Evaluation of all gain options for the INA185
• Ease of access to device pins with test points
• Capability to evaluate high-side and low-side configurations
• Capability to provide a buffered reference through a user defined voltage divider
See the INA185 data sheet (SBOS378) for comprehensive information about the INA185 family of
devices.
3 Quick Start Setup and Use
The following instructions show how to set up and use the INA185 devices with the INA185EVM. For the
circuits in the following instructions, x = A to D.
Step 1. Connect an external dc supply voltage between 2.7-V and 5.5-V to the VCC test point TP2x,
and connect the ground reference of that supply to one of the GND test points: TP7x, TP8x,
or TP9x.
Step 2. The REF pin is connected to the GND pin in the default board. The voltage applied at the
reference input varies depending on how the device is going to be used. Further details
regarding the use of the reference voltage are discussed later in this document.
Step 3. Connect the input as described in Section 3.1.
3.1 Measurements
The INA185EVM can either simulate the voltage developed across a sense resistor based on a given set
of system conditions, or connect remotely to an existing shunt already included in a user application.
The following procedures are used to configure a measurement evaluation without a shunt. For the circuits
in the following instructions, x = A to D.
Step 1. Connect a differential voltage to the IN+ (TP6x) and IN– (TP3x) test points. With the
reference voltage set at ground, make sure that the IN+ pin is the more positive of the two
inputs.
Step 2. Measure the output voltage at the OUT test point (TP4x or TP5x).
NOTE: The output voltage is equal to the gain of the device multiplied by the differential voltage
measured directly at the device input pins.

4 Circuitry
This section summarizes the INA185EVM components. For the following circuits, x = A to D.
4.1 C1x, J1x, R1x, and TP1x
C1x and R1x form a low-pass RC filter to the source that supplies the INA185 REF pin. By default, no
filter is installed, with R1x shorted by a 0-Ωresistor, and C1x not populated. J1x is a jumper that
conveniently allows the user to short the INA185 reference to ground, connect directly to an external
power supply, or short to a voltage set by a buffered voltage divider.
4.2 C2x and C3x, and TP2x
C2x is a 0.1-µF supply bypass capacitor for the INA185, U1x. The C2x footprint size, 0201, was chosen in
order to reduce overall layout size. A 0.1-µF capacitor is required for proper operation of the INA185, and
the user typically will not need to replace or adjust C2x. C3x is a footprint for an additional supply bypass
capacitor that the user can populate to further stabilize the supply. TP2x allows the user to connect an
external supply to the INA185 VS pin.
4.3 C4x
C4x is a 0.1-µF supply bypass capacitor for the optional INA185 reference pin buffer, U2x.
4.4 C5x, R2x, and R4x
C4x, R2x, and R4x form a differential mode filter to the input of the INA185, U1x. By default, this filter is
not installed, with R2x and R4x shorted by a 0-Ωresistor, and C4x not populated. If this filter is installed,
R2x and R4x must be less than 10 Ωwith low tolerance (≤1%) in order to minimize measurement error.
4.5 C6x, R3x, TP4x, and TP5x
C3x and R3x form a low-pass filter on the output of the INA185, U1x. By default, no filter is installed with
R3x shorted by a 0-Ωresistor, and C6x not populated. TP4x shows unfiltered output. By default, TP5x
also shows unfiltered output, but with R3 and C6 populated, TP5x shows filtered output.
4.6 C7x, R5x, and R6x
C7x and R5x form a low-pass filter to the input of the optional reference buffer. R5x and R6x form a
voltage divider that sets a desired reference voltage.
4.7 U1x
U1x is the INA185 current shunt monitor. Four gain-option segments are supplied within the INA185EVM
board. Each segment is populated with one of the available device gains. This configuration enables users
to test the devices and determine the best gain setting for a given application. For x = A to D, the gain is
20 V/V, 50 V/V, 100 V/V, and 200 V/V, respectively.
The following is a list of the factors involved in selecting the appropriate device:
• The differential input voltage is applied across the inputs, or developed based on the load current that
flows through the shunt resistor.
• The limiting factor that requires attention to be given to device selection is the output voltage.
• The selected device must allow the output voltage to remain within the acceptable range after the
developed input voltage is amplified by the respective device gain. The output voltage must remain
within the range of 10 mV greater than ground to 100 mV less than the supply voltage.
• An output less than the minimum allowable output requires a device with a higher gain. Likewise, an
output greater than the maximum allowable output requires a device with a lower gain.
4.8 U2x
U2x is a SOT-23 footprint for a buffer amplifier. By default, this part is not populated.

5 Reference Voltage Setup
The INA185 allows for the use of an external reference. This reference determines how the output
responds to certain input conditions. The reference also enables these devices to be used in unidirectional
and bidirectional applications.
5.1 Unidirectional Mode
Unidirectional refers to a load current that flows in only one direction.
By default, each EVM board segment (one segment for each gain option) has the INA185 REF pin
connected to GND through a 0-Ωresistor and a jumper. This connection sets the INA185 for unidirectional
measurements. If bidirectional measurements are required, the EVM board segments can be modified to
add external voltages to the REF pins.
5.2 Bidirectional Mode
Bidirectional refers to a load current that flows in both directions.
The INA185 is able to measure bidirectional currents. The ability to measure current flowing in both
directions is enabled by applying a voltage to the REF pin. The voltage applied to REF sets the output
state that corresponds to the zero-input-level state. The output then responds by increasing to greater
than REF for positive differential signals (relative to the IN– pin), and by decreasing to less than REF for
negative differential signals. This reference voltage applied to the REF pin can be set anywhere from 0 V
to V+. For bidirectional applications, REF is typically set at midscale for an equal signal range in both
current directions. However, REF is set at a voltage other than midscale when the bidirectional current
and corresponding output signal do not have to be symmetrical.
5.3 REF Pin Configuration
Jumper connection J1x configures the respective EVM board segment for either unidirectional or
bidirectional operation. Shorting the left and middle pins of J1x sets the board for unidirectional
measurements. Removing the jumper and applying a voltage between 0 V to V+ to the middle pin of J1x
sets the board to a bidirectional measurement with the zero current output centered at the applied voltage.
Alternatively, install C4x, R5x, R6x, and U2x to provide a buffered voltage divider input from the supply to
set the reference voltage. For the buffered divider, install the jumper on the middle and right pins of J1x.
