1 Overview
The INA4180 family of current-shunt monitors (also called current-sense amplifiers) can sense drops
across shunts at common-mode voltages from –0.2 V to +26 V, independent of the supply voltage. Four
fixed gains are available: 20 V/V, 50 V/V, 100 V/V, and 200 V/V. The INA4181 family has the same
capabilities as the INA4180 family but with the addition of reference pins on each channel that enables
bidirectional current measurements. These devices operate 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 INA4180 devices are currently available in a TSSOP(14) and the INA4181 devices are available in a
TSSOP(20) surface-mount packages. Table 1 lists the available gain options.

INA4180-INA4181 Evaluation Module User's Guide
The following is a list of the factors involved in selecting the appropriate device:
• The INA4180A1-A4 devices are identical with the exception of different gain settings. The INA4181A1-
A4 devices have the same device gain options of the INA4180 but with the addition of the reference
pin that enables bidirectional current measurements.
• Select INA4180 for unidirectional applications only, and select INA4181 for unidirectional or
bidirectional applications.
• The differential input voltage is applied across the inputs, or developed based on the load current that
flows through the shunt resistor.
• A significant 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 input
voltage is amplified by the device gain. The output voltage must remain within the range of 10 mV
above ground to 100 mV below the supply voltage.
• An output below the minimum allowable output requires the selection of a device with a higher gain.
Likewise, an output above the maximum allowable output requires the selection of a device with a
lower gain.
4.4 Voltages Inputs(IN+1, IN–1, IN+2, IN–2, IN+3, IN-3, IN+4, IN-4)
The IN+1 and IN–1 inputs accept a differential voltage that is amplified by the selected device gain and is
presented at the OUT1 test point. These inputs can also be used to connect the differential voltage
developed across an external shunt in an existing circuit. The acceptable differential input voltage range
and polarity are determined by the supply voltage, reference voltage, and gain of the selected device.
4.5 Reference Voltage pins (REF1, REF2, REF3, REF4)
REF1 test points enables the user to configure the INA4181A1-A4 device boards for either unidirectional
or bidirectional operation. Refer to Section 4.6 for more information.
4.6 Reference Voltage Setup
The INA4181A1-A4 devices enable the use of an external reference, REF1. 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. The REF1 pin can also be connected to supply (VS) to
enable unidirectional measurement in the negative direction.
4.6.1 Rx10, Rx11, Rx12 and Rx13
Rx10 resistors locations are not populated. If a 0-Ωresistor is populated, the REF1 pin will be connected
to GND, and the INA4181 can be used for unidirectional measurements. These locations allow for 0805
surface-mount package size.
4.6.2 Unidirectional Mode
Unidirectional refers to a load current that flows in only one direction.
The INA4180A1-A4 devices are able to measure unidirectional currents only. The INA4181A1-A4 devices
measure unidirectional and bidirectional currents. For unidirectional measurements, connect the REF1 pin
to GND. You can connect the REF1 pin to GND through a 0-Ωresistor (Rx10) or ground it directly with the
test point.
4.6.3 Bidirectional Mode
Bidirectional refers to a load current that flows in both directions.

INA4180-INA4181 Evaluation Module User's Guide
The INA4181A1-A4 are able to measure bidirectional currents. The ability to measure this current flowing
in both directions is enabled by applying a voltage to the REF1 pin. The voltage applied to REF1 sets the
output state that corresponds to the zero-input level state. The output then responds by increasing above
REF1 for positive differential signals (relative to the IN–1 pin) and responds by decreasing below REF1 for
negative differential signals. This reference voltage applied to the REF1 pin can be set anywhere from 0 V
to VS. For bidirectional applications, REF1 is typically set at mid-scale for equal signal range in both
current directions. In some cases, however, REF1 is set at a voltage other than mid-scale when it is
unnecessary that the bidirectional current and corresponding output signal be symmetrical.

and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for
successful communication. This radio transmitter has been approved by Industry Canada to operate with the antenna types
listed in the user guide with the maximum permissible gain and required antenna impedance for each antenna type indicated.
Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited
for use with this device.
Concernant les EVMs avec antennes détachables
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et
d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope
rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. Le
présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés dans le
manuel d’usage et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne
non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de
l'émetteur
