描述
The ISL28433TSSOPEVAL1Z 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.
特性
- Single-supply operation: +1.65V to +5.5V
- Dual-supply operation: ±0.825V to ±2.75V
- Single-ended or differential input operation with high gain (G = 10,000V/V)
- External voltage reference (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
