User's Guide SBOU083 – September 2010 INA282-INA286EVM This user’s guide describes the characteristics, operation, and use of the INA282-286EVM evaluation module (EVM). This EVM is designed to evaluate the performance of the INA282-286 family of voltage output current shunt monitors. This EVM has a flexible configuration, allowing for user evaluation suitable to a variety of applications. -
Page 2: Introduction And Overview
The INA282-286EVM allows the user to install a shunt resistor, and then connect both the common-mode voltage and load to develop the input voltage, or to omit the shunt resistor and apply a differential voltage directly to the device input. -
Page 3: Hardware Included With The Ina282-286Evm
Introduction and Overview www.ti.com Hardware Included The INA282-286EVM features the SOIC-packaged version of the INA28x. Device boards populated with each of the available gain versions of the INA282 family of devices will be provided in all INA282-286EVM delivered, as Figure 1 shows. -
Page 4: Quick Start Setup And Use
Quick Start Setup and Use Follow these procedures to set up and use the INA282-286EVM. Step 1. Insert the device board to be evaluated into the U1 location. The U1 location allows the user to either evaluate one of the provided device boards or to install the test device directly on the surface-mount pads in the U1 footprint. -
Page 5: Measurement Without Shunt
This connection method allows the user to either simulate the voltage developed across a sense resistor based on a given set of system conditions, or to connect the INA282-286EVM remotely to an existing shunt already included in an example application. -
Page 6: Ina282-286Evm Circuit
INA282-286EVM Circuit This section summarizes the INA282-286EVM components. R1 can be used for shunt resistors that have a package that is not easily adaptable to a standard, two-terminal, through-hole footprint or to a 0603 through 1206 surface-mount footprint. Specifically, this component location was added to allow for the use of TO-126, TO-220, TO-247, and four-terminal inline radial packages such as the CS3 series of shunts from Ohmite. - Page 7 INA282-286EVM Circuit www.ti.com Figure 6.

Page 9: U1 Populated With Dip Board
INA282-286EVM Circuit www.ti.com U1 is the location for the test device. Five device boards are supplied with this INA282-286EVM board; each device board is populated with one of the available device gains. This interchangeable option allow users to test the devices and determine the gain setting that is best suited for a given application. -
Page 10: Reference Voltage Setup
Miscellaneous The REF1 and REF2 terminals of T3 allow the user to configure the INA282-286EVM for either unidirectional or bi-directional operation. Two easily-accessed oscilloscope ground pads are located on the PCB to facilitate easier probing. -
