Quad Micropower, Chopper Stabilized, RRIO Op Amp Evaluation Boards


The ISL28433SOICEVAL1Z and ISL28433TSSOPEVAL1Z evaluation boards are 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
