STMicroelectronics TSV781 & TSV782
TSV781 & TSV782 - High bandwidth (30 MHz) low offset (200 µV) rail-to-rail 5 V op amp
The TSV78x is a 30 MHz-bandwidth unity-gain-stable amplifier. The rail-to-rail input stage and the slew rate of 20 V/µs make the TSV78x ideal for low-side current measurement.
The TSV78x can operate from 2.0 V to 5.5 V single supply and it is fully specified on a load of 47 pF, therefore allowing easy usage as A/D converters input buffer. The TSV78x series offers rail-to-rail input and output, excellent speed/power consumption ratio, and 30 MHz gain bandwidth product, while consuming just 3.3 mA at 5 V.
The devices also feature an ultra-low input bias current that enables connection to photodiodes and other sensors where current is the key value to be measured.
These features make the TSV78x series ideal for high-accuracy, high-bandwidth sensor interfaces.
