The ISL28005 and ISL28006 are ground-sensing current sense amplifiers that amplify millivolt current signals developed across sub-1Ω sense resistors.

The ISL28005 sub-family of lower cost amplifiers for general (current) sensing applications featuring measurement accuracies better than 4% and input offset voltages less than 500μV over the -40 °C to +125 °C temperature range.

For greater precision, the ISL28006 sub-family offers gain accuracy and input offset voltages as low as 1% and 300μV over the full temperature range, depending on the device.

The ISL28005/6 evaluation board is a design platform containing all the circuitry needed to characterize critical performance parameters of the ISL28005/6 in either a high-side or low-side current sense application. The ISL28005/6 is available in fixed 100V/V, 50V/V, 20V/V gains.
