This user's guide describes the characteristics, operation, and use of the evaluation module (EVM) for the
INA826. The EVM is designed to evaluate the performance of the device in both single and dual-supply
configurations. This document also includes the schematic, printed circuit board (PCB) layouts, and a
complete bill of materials (BOM). Throughout this document the terms evaluation board, evaluation
module, and EVM are synonymous with the INA826EVM.

Quick Start www.ti.com Quick Start The procedures presented in this section describe how to quickly set up and use the INA826EVM for evaluation in dual-supply and single-supply configurations. Dual Supply Make the following connections to set up the INA826EVM for dual-supply operation. - Page 5 Quick Start www.ti.com Single Supply Make the following connections to set up the INA826EVM for single-supply operation with a direct connection for the reference voltage. 1. +5 V to V+ test point 2. GND to V– test point 3. +2.5 V to REF test point 4.
- Page 6 Quick Start www.ti.com Make the following connections to set up the INA826EVM for single-supply operation with a buffered reference voltage. This example uses an OPA376 as the buffer operational amplifier. Depending on the application, alternate single-supply buffer operational amplifiers include the OPA330 and OPA378.

EVM Components www.ti.com EVM Components This section summarizes the INA826EVM components. Power Power is applied to the INA826 with test points V+ and V–. For the unpopulated device (U2), power is applied using test points OAV+ and OAV–. Inputs Inputs are applied to the INA826 using test points V+IN and V–IN. Alternately, they can be applied by populating the input SMA connectors (J1 and J2). -
