TSV782IYDT

TSV782IYDT is a 2-channel, high bandwidth, low offset, unity-gain-stable amplifier. The rail-to-rail input stage and the slew rate make the TSV782 ideal for low-side current measurement. It can operate from 2.0V to 5.5V single supply and it is fully specified on a load of 47pF, therefore allowing easy usage as A/D converters input buffer. It offers rail-to-rail input and output, excellent speed/power consumption ratio, and 30MHz gain-bandwidth product, while consuming just 3.3mA at 5V. It features an ultra-low input bias current that enables connection to photodiodes and other sensors where current is the key value to be measured. It is ideal for high-accuracy, high-bandwidth sensor interfaces. Application includes high bandwidth low-side and high-side current sensing, photodiode transimpedance amplification, A/D converters input buffers, power management in solar-powered systems, and power management in HEV and EV.
