1 Description

INA187EVM and INA299EVM are small modules with three completely independent boards that can be broken off by the designer. Three schematically identical boards are available for each of the three gain variations of the INA187EVM and INA299EVM with inputs up to 42V and 80V common-mode respectively and 10A (onboard shunt) input capability.

Each board provides test points for VS, GND, OUT and a terminal block of Vin+ and Vin-. Pads and sockets allow for quick implementation of input and output filtering as well as an onboard 2512-size shunt resistor.
