The ISL28433SOICEVAL1Z evaluation board is designed to evaluate the performance of the ISL28433 chopper stabilized op amp. The ISL28433 chopper stabilized rail-to-rail quad op amp features a low 8μV maximum VOS over-temperature and a 0.1Hz 1/f noise corner frequency, enabling very high gain single-stage DC amplifiers that can operate from single cell batteries while consuming only 20μA of current. Each evaluation board can be configured as a precision high-gain (G = 10,000V/V) differential amplifier and demonstrates the level of performance possible with this type of amplifier while operating from battery voltages as low as 1.65V.


  • Single supply operation: +1.65V to +5.5V
  • Dual supply operation: ±0.825V to ±2.75V
  • Singled-ended or differential input operation with high gain (G = 10,000V/V)
  • External VREF input
  • Banana jack connectors for power supply and VREF inputs
  • BNC connectors for op amp input and output terminals
  • Convenient PCB pads for op amp input/output impedance loading


  • Bidirectional current sense
  • Temperature measurement
  • Medical equipment
  • Electronic weigh scales
  • Precision/Strain gauge sensor
  • Precision regulation
  • Low ohmic current sense
  • High gain analog front ends
