STMicroelectronics unit-gain stabilized amplifier

STMicroelectronics's TSV771 is a 20 MHz bandwidth unit-gain stabilized amplifier. The rail-to-rail input stage and 10.5V /µs conversion rate make it ideal for low-side current measurements.

The excellent accuracy provided by the maximum input voltage of 200μV allows precise amplitude-size input signals. The TSV771 can operate on a single power supply from 2.0V to 5.5V and has an output capacitance of 47 pF, making it easy to use as an input buffer for a /D converters.
