Low-Side, Bidirectional, Precision Current Sense Op Amp Evaluation Board

The ISL28134ISENSEV1Z evaluation board is designed specifically for low-side bidirectional current sensing up to 10A of current. The evaluation board uses a 1mΩ current sense resistor capable of handling 4W of power dissipation.

The ISL28134 is a single, chopper-stabilized zero-drift operational amplifier optimized for single and dual supply operation from 2.25V to 6.0V and ±1.125V and ±3.0V. The ISL28134 uses auto-correction circuitry to provide very low input offset voltage, drift, and a reduction of the 1/f noise corner below 0.1Hz. The ISL28134 achieves ultra-low offset voltage, offset temperature drift, wide gain bandwidth, and rail-to-rail input/output swing while minimizing power consumption.
