This user's guide describes the characteristics, operation, and use of the INA190 evaluation module
(EVM). This EVM is designed to evaluate the performance of the
monitor in a variety of configurations. This document also includes a schematic, reference printed-circuit
board (PCB) layouts, and a complete bill of materials (BOM).

Page 3: Overview
(EMC) testing. The INA190EVM consists of one PCB with an option to cut out six individual PCBs, one for each of the five gain variants (INA190A1, INA190A2, INA190A3, INA190A4, and INA190A5). Each of the PCB cutouts consists of one INA190AXIRSW device (where x is 1, 2, 3, 4, and 5) and test points for external hardware connections, as well as pads to solder down optional circuitry. -
Page 4: Quick Start Setup And Use
Quick Start Setup and Use Follow these procedures to set up and use one of the panels of the INA190EVM. For the following instructions, x = 1, 2, 3, 4, 5, or [blank]. Step 1. Choose the desired gain option panel. -

INA190EVM Circuit and Components www.ti.com INA190EVM Circuit and Components This section summarizes the INA190EVM components. For the following instructions, x = 1 to 5 or a [blank]. R5x, R6x, R7x, R3x,C2x, C3x, C4x, C9x R5x, R6x, R7x, and R3x are factory-installed 0-Ω resistors. C2x, C3x, C4x, and C9x are not populated except for C9x. -
Page 6: Reference Voltage Setup
Reference Voltage Setup The INA190 devices allow for the use of an external reference through the REF pin. The INA190EVM provides a test point to drive the REF pin externally or pads to solder a buffer amplifier to drive a custom voltage generated from the resistor divider off the VS power plane. -
Page 7: Guarding Voltage - Using The "Guarded Inputs" Panel
Guarding Voltage - Using the "Guarded Inputs" Panel One panel on the INA190EVM is labeled as "Guarded Inputs" because it includes extra circuitry to help guard the input traces going into the IN+ and IN– pins of the INA190. When measuring a small current, it is desirable to minimize the input bias currents of the device, which is in the nanoamps. -
