The family of the amplifier are single/dual/quad chopper-stabilized zero-drift operational amplifiers optimized for single or dual supply operation from 1.8 V to 5.5 V and ±0.9 V to ±2.75 V. TP555X features very low input offset voltage and low noise with no 1/f noise corner down to 0.1 Hz. 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.

This TP555X family can provide very low offset voltage (max 5 μV) and near-zero drift over time and temperature with excellent CMRR and PSRR. The TP5551 (single version) is available in SOT23-5, and SOP8 packages. The TP5552 (dual version) is offered in MOSP8, SOP8 package. The TP5554 (quad version) is available in TSSOP14, SOP14 package. All versions are specified for operation from −40°C to 125°C.
