Typical Application

The TP555x in Thermistor Measurement


The TP555x op-amps are single/dual/quad chopper stabilized zero-drift operational amplifier optimized for single or dual supply operation from 1.8V to 5.5V and ±0.9V to ±2.75V. The TP555x features very low input offset voltage and low noise with 1/f noise corner down to 0.1Hz. The TP555x is designed to have ultra low offset voltage and offset temperature drift, wide gain bandwidth and rail-to-rail input/output swing while minimizing power consumption.

The TP555x family can provide very low offset voltage (5μV Max.) and near-zero drift over time and temperature with excellent CMRR and PSRR.

The TP5551 (single version) is available in SOT23, SC70 and SO-8 packages. The TP5552 (dual version) is offered in MSOP-8 and SO-8 packages. The TP5554 (quad version) is available in TSSOP-14 and SO-14 packages. All versions are specified for operation from -40°C to 125°C.
