The ISL28134SOICEVAL1Z evaluation board is designed to evaluate the performance of the ISL28134 low noise chopper stabilized op amp. The evaluation board contains the circuitry needed to evaluate the high performance of the ISL28134 amplifier. The ISL28134 chopper stabilized rail-to-rail input/output (RRIO) amplifier features a low 2.5µV maximum VOS and 15nV/°C drift over-temperature. The amplifier has no 1/f noise corner down to 0.1Hz with a 1kHz voltage noise density of 10nV/√Hz. The high open loop gain of 174dB allows a high gain single-stage DC amplifier that can operate from a 3V single cell battery while consuming 700µA of current. The ISL28134SOICEVAL1Z evaluation board can be configured as a precision high-gain (G = 1,000V/V) differential amplifier to demonstrate the level of performance possible with this amplifier.
