The TSV771, TSV772 and TSV774 are single, dual and quad 20 MHz-bandwidth unity-gain-stable amplifiers. The rail-to-rail input stage and the slew rate of 10.5 V/µs make the TSV771, TSV772 and TSV774 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, TSV772 and TSV774 can operate from a 2.0 V to 5.5 V single supply and are fully characterized for an output capacitor of 47 pF, therefore allowing easy usage as A/D converters input buffer.
