Description
The TSV791, TSV792 and TSV794 are single, dual and quad 50 MHz-bandwidth unity-gain-stable amplifiers. The rail-to-rail input stage and the slew rate of 30 V/µs make the TSV79x ideal for low-side current measurement. The excellent accuracy provided by maximum input voltage of 200 µV allows amplifying accurately smallamplitude input signal. The TSV79x can operate from a 2.2 V to 5.5 V single supply; it can typically handle an output capacitor up to 1 nF and is fully specified on a load of 22 pF, therefore allowing easy usage as A/D converters input buffer.
