The STMicroelectronics TSV7721, TSV7722 and TSV7723 are single and dual 22 MHz-bandwidth unity-gain-stable amplifiers. The input offset voltage of 200 μV max. (50 μV typ.) at room temperature, optimized for common-mode close to ground makes the TSV772x ideal for low-side current measurements. The TSV772x can operate from 1.8 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 TSV772x series offers rail-to-rail output, excellent speed/power consumption ratio, and 22 MHz gain bandwidth product, while consuming just 1.7 mA at 5 V.

Gain bandwidth product 22 MHz, unity gain stable
High accuracy input offset voltage
Low input bias current
Output rail-to-rail
Input common-mode range includes low rail
Automotive grade and shutdown versions available

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 TSV772x series ideal for high-accuracy, high-bandwidth sensor interfaces.
