Description：

The TP5591/TP5592/TP5594 is a series of single,dual and quad chopper-stabilized zero-drift operationalamplifiers optimized for single or dual supply operationfrom 1.8 V to 5.5 V or ±0.9 V to ±2.75 V. The TP559xseries features a very low input offset voltage and lownoise with the 1/f noise corner down to 0.1 Hz. Theseries is designed to have a low offset voltage andoffset temperature drift, a wide gain bandwidth, and arail-to-rail input and output swing while minimizing powerconsumption.The TP559x series can provide a low offset voltage (20 μVmax) and a near-zero drift over time and temperature withexcellent CMRR and PSRR.The TP5591 (single version) is available in the SOT353(SC70-5), SOT23-5, and SOP8 packages. The TP5592(dual version) is offered in the MSOP8 and SOP8packages. The TP5594 (quad version) is available in theTSSOP14 and SOP14 packages. All versions are specifiedfor operation from −40°C to 125°C.
