Typical Application

The TP559x in Single Supply, High Gain Amplifier (AV = 10,000 V/V) Application


The TP5591-2-4 amplifiers are single, dual and quad chopper stabilized zero-drift operational amplifiers optimized for single or dual supply operation from 1.8V to 5.5V or ±0.9V to ±2.75V. The TP559x op-amps feature very low input offset voltage and low noise with 1/f noise corner down to 0.1Hz. The TP559x amplifiers are designed to have low offset voltage and offset temperature drift, wide gain bandwidth and rail-to-rail input and output swing while minimizing power consumption. 

The TP559x op-amps can provide low offset voltage (20μV Max) and near-zero drift over time and temperature with excellent CMRR and PSRR. 

The TP5591 (single version) is available in SC70-5, SOT23-5 and SO-8 packages. The TP5592 (dual version) is offered in MSOP-8, SO-8 package. The TP5594 (quad version) is available in TSSOP-14 and SO-14 package. All versions are specified for operation from -40°C to 125°C.
