Overview
The TSV772IQ2T is a dual operational amplifier produced by STMicroelectronics. It is part of the TSV771, TSV772, and TSV774 family, which includes single, dual, and quad 20 MHz-bandwidth unity-gain-stable amplifiers. The TSV772IQ2T features a rail-to-rail input stage and a high slew rate, making it ideal for applications such as low-side current measurement and high-frequency signal conditioning. It operates from a single supply voltage ranging from 2.0 V to 5.5 V and is fully characterized for use with an output capacitor of 47 pF, facilitating its use as an input buffer for A/D converters.
