TSZ121ILT ST Precision Op-Amp | SOT-23-5 | 5µV Offset, 0.1µV/°C Drift

Product Overview

The TSZ121ILT from STMicroelectronics is a high-precision, zero-drift operational amplifier in a compact SOT-23-5 package. It offers an ultra-low input offset voltage of 5 µV (max) and a typical offset drift of 0.1 µV/°C, making it ideal for applications requiring high accuracy over temperature. The device operates from a single supply voltage of 1.8 V to 5.5 V and features rail-to-rail input and output. Its low power consumption (235 µA typical) and small footprint enable use in space-constrained, battery-powered systems.
