TSU111IYCT ST Operational Amplifier | SOT-323-5 | 1.5V-5.5V, 1.2µA

Product Overview

The TSU111IYCT from STMicroelectronics is a high-performance, ultra-low-power operational amplifier in a compact SOT-323-5 package. It is designed for applications requiring precision signal conditioning with minimal power consumption. The device operates from a single supply voltage ranging from 1.5V to 5.5V, making it ideal for battery-powered and portable equipment. With a typical supply current of only 1.2µA, it extends battery life in IoT sensors, wearable devices, and medical monitors. The rail-to-rail input and output capability ensures maximum dynamic range even at low supply voltages.
