The INA79x is a wide-common mode current-sense amplifier that provides ease-of-use and high performance. The INA79xEVM is a family of EVMs intended to provide basic, functional evaluation of all INA79x variants.

The INA79xEVM is populated with either of INA790A, INA790B, INA791A or INA791B device. Each of the variants is a unique orderable, and can be ordered from the corresponding product folder. The EVM allows testability of the adjustable gain and options for driving the reference pin.

Across all EVM variants, the parts that can be examined with the EVM are:

  • INA790A
  • INA790B
  • INA791A
  • INA791B
