Description

The TSV771 and TSV772 are a single and dual 20 MHz-bandwidth unity-gain-stable

amplifier. The rail-to-rail input stage and the slew rate of 10.5 V/µs make the

TSV771 and 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 TSV771 and 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, therefore allowing easy usage as A/D

converters input buffer.
