TSV7722IDT

TSV7722IDT is a dual channel, 22MHz-bandwidth, low offset, low-rail unity gain-stable amplifier. It operates from 1.8V to 5.5V single supply and it is fully specified on a load of 47pF, therefore allowing easy usage as an A/D converter input buffer. It offers rail-to-rail output and, an excellent speed/power consumption ratio. It also features an ultra-low input bias current that enables connection to photodiodes and other sensors where current is the key value to be measured. This feature makes the device ideal for high-accuracy, high-bandwidth sensor interfaces. It is used in applications such as low-side current measurement, photodiode amplifiers, automotive current measurement and sensor signal conditioning, strain gauges signal conditioning.
