DESCRIPTION
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 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.
