TS951ILT Low Power SOT-23 Rail-to-Rail Op Amp, Single Channel

The TS951ILT from STMICROELECTRONICS is a low-power, single-channel operational amplifier featuring rail-to-rail input and output (RRIO) capabilities. Designed with BiCMOS technology, it is fully optimised and specified for operation at 3V and 5V, making it an ideal choice for power-sensitive applications. Its low quiescent current of just 0.9mA at 3V ensures minimal power consumption, significantly extending battery life in portable systems.

This op amp offers excellent precision with an input offset voltage of 6mV and a low drift of just 2μV/°C. It maintains a high supply voltage rejection ratio of 80dB, ensuring stable performance despite variations in the power supply. With a gain bandwidth product of 3MHz and a slew rate of 1V/µs, it provides sufficient speed for a wide range of signal conditioning and buffering tasks.
