Description
The TSV7721, TSV7722 and TSV7723 are single and dual 22 MHz-bandwidth unitygain-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. 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. Maturity status link Channel Automotive
