描述 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 smallamplitude

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.

Applications

• High bandwidth low-side and high-side current sensing

• Photodiode amplifiers

• A/D converters input buffers

• Power management in solar powered systems

• Automotive high bandwidth signal conditioning

• Active filters
