The STMicroelectronics high bandwidth low offset rail to rail 5V Op amp is a dual 20 MHz-bandwidth unity-gain-stable amplifier. The rail-to-rail input stage and the slew rate of 13 V/μs make the TSV772 ideal for low-side current measurement. The excellent accuracy provided by maximum input voltage of 200 μV allows amplifying accurately small-amplitude input signal. The TSV772 can operate from a 2.0 V to 5.5 V single supply and is fully characterized for an output capacitor of 47 pF, for easy usage as an A/D converter input buffer.
