TSV772IQ2T

TSV772IQ2T is a dual 20MHz-bandwidth, low offset, low-rail unity gain-stable amplifier. The rail-to-rail input stage makes the device ideal for low-side current measurement. The excellent accuracy provided by maximum input voltage of 200µV allows amplifying accurately small-amplitude input signal. It operates from a 2V to 5.5V single supply and are fully characterized for an output capacitor of 47pF, therefore allowing easy usage as A/D converters input buffer. It is used in applications such as 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.
