STMICROELECTRONICS TSV794IDT Operational Amplifier, 4 Channels, 50 MHz, 30 V/µs, 2.2V to 5.5V, SOIC, 14 Pins

TSV794IDT is a quad-channel, 50MHz-bandwidth unity-gain-stable amplifier. The rail-to-rail input stage and the slew rate of 30V/µs make the device ideal for low-side current measurement. The excellent accuracy provided by maximum input voltage of 200µV allows amplifying accurately small amplitude input signal. It can operate from a 2.2V to 5.5V single supply. It is used in applications such as high bandwidth low-side and high-side current sensing, photodiode transimpedance amplification, A/D converters input buffers, power management in solar-powered systems, and power management in automotive applications.
