1 Introduction
For use in high-resolution voltage measurement applications, the high-impedance input of the AMC1311 is
optimized for connection to high-voltage resistive dividers or other voltage signal sources with high output
resistance.
Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with
the AMC1311EVM.
1.1 Features
• Full-featured Evaluation Module for the AMC1311 single-channel precision isolation amplifier.
• Screw terminals for easy access to analog inputs and outputs.
• Transformer and rectifiers to provide an isolated 5-V source to VDD1.
• Differential to Single-ended output option.
2 Analog Interface
The analog input to the AMC1311 is routed from a three-wire screw terminal screw at J1.1 which provides
access to the VINP terminal. A test point, TP1 is also provided along with pads for 1206 size user installed
series resistors R1, R2 and R3 to create a voltage divider circuit for the input to the AMC1311. The analog
input is referenced to J1.2 or TP2.
2.1 Analog Input
The default analog input to the AMC1311EVM board is comprised of R4 and C3 which form a simple anti-
aliasing filter with a corner frequency of 723 Hz. The input circuit for the AMC1311 is shown in Figure 1.
Using a signal generator or other voltage source, the user can apply an input signal directly to J1 pin 1.
The maximum voltage input to the AMC1311 via J1.1 is 2 V referenced to J1.2 or TP2.

With user installed resistor options R1 through R3, an external voltage source can be applied between
TP1 and GND1 via J1.2 or TP2. As depicted in Figure 1, with R4 installed as 10 kΩ, resistors R1 through
R3 can be chosen according to Equation 1:
(1)
2.2 Shutdown
The AMC1311 features a shutdown option which is an active high input. Shunt jumper SH-J7 is installed
by default and allows for normal operation of the AMC1311 device. When the shunt jumper is removed,
the AMC1311 enters into a low power mode by means of an internal pullup resistor for battery or other
power sensitive applications. For external shutdown operation, J1.3 provides access to the SHTDN pin
when shunt SH-J7 is removed.
2.3 Analog Output
The analog output from the AMC1311EVM board is a fully differential signal centered at 1.44 V. The
differential output of U1 is available on the two screw terminals of J2 as shown below in Figure 2. U4 and
U5 provide the user with a single-ended version of the analog output on J6 pin 1. U5 is designed to
provide bias voltage to the difference amplifier configuration of U4. The single ended output provides unity
gain with an output voltage swing from 0.5 V to 2.5 V. If a different bias voltage is desired, the shunt on J8
can be moved to cover pins 2-3 and an external voltage source may be applied to TP4 referenced to
GND2 via TP3.

3 Power Supplies
The AMC1311EVM requires two separate power rails, VDD1 and VDD2. VDD1 is on the high voltage side
of the amplifier. VDD2 is on the user side of the amplifier.
3.1 VDD1 Input
The default configuration of the EVM provides 5V to VDD1 through transformer T1 via U3, an SN6501
push-pull driver. A shunt on jumper J5 is shorting pins 1-2 which routes the regulated 5V from U2, a
TPS76350, to pin 1 of U1. The screw terminal at J4 allows the user to provide their own VDD1 source
when the shunt on J5 is covering pins 2-3. The VDD1 supply should be between 3 and 5.5 VDC when
using an external voltage source. The input power scheme is shown in Figure 3.
Figure 3. VDD1 Input
3.2 VDD2 Input
The user side of the AMC1311 isolation amplifier is rated for 3.0 to 5.5 VDC and is applied to the amplifier
using J3 pin 1. When using the on-board transformer for VDD1, a minimum of 3.6 V is needed at J3.
Figure 4 depicts the power input for VDD2.
