INA281 -4-V to 110-V, 1.3-MHz current sense amplifier evaluation module


Order now


This is a small module with 10 completely independent boards that can be broken off by the user. Ten schematically identical boards for each of the five gain variation and two pinout variations of the INA281 with inputs up to 110V common mode and 5A (on board 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 filter and output filtering and an onboard 2512 size shunt resistor.

  • Easy to test INA281 with differential voltage or shunt resistor.
  • Pads and sockets allow quick and easy implementation of SMD filtering.
  • Breakable panels lets customer experiment and test with all gain variants and two pin outs.
