ISL2813xxSENSEV1Z

Low Side, Bi-directional, Precision Current Sense Op Amp Eval Boards

Description

The ISL28130ISENSEV1Z, ISL28133CSENSEV1Z, ISL28133ISENSEV1Z and ISL28134ISENSEV1Z evaluation boards are designed specifically for low side bi-directional current sensing up to 10A of current. The evaluation boards use a 1mΩ current sense resistor that is capable of handling 4W of power dissipation. These evaluation boards are separated into three categories: low cost (ISL28130ISENSEV1Z), low power (ISL28133CSENSEV1Z, ISL28133ISENSEV1Z) and low noise (ISL28134ISENSEV1Z).

The ISL28133CSENSEV1Z is designed specifically for low side current sensing applications up to 10A of current, while the ISL28133ISENSEV1Z uses the ISL28133 chopper amplifier in a high side, low side of floating supply current sense application.
