Description

The TSU111H operational amplifier (op amp) offers an ultralow power consumption of

1.7 µA typical and 2.4 µA maximum when supplied by 1.8 V.

The ultralow power consumption, the high accuracy of 250 µV max., and 23 kHz

gain bandwidth make the TSU111H ideal for sensor signal conditioning, battery

management systems, onboard (OBC) and wireless chargers.
