Description

The TSU111 operational amplifier (op amp) offers an ultra low-power consumption 900 nA typical and 1.2 A maximum when supplied 3.3 V. Combined with a supply voltage range 5.5 V, these features allow the to be efficiently supplied by a coin type Lithium battery or a regulated voltage in low-power applications. The high accuracy 150 V max and 11.5 kHz gain bandwidth make the TSU111 ideal for sensor signal conditioning, battery supplied, and portable applications.

More than 25 years of typical equivalent lifetime supplied a 220 mA.h CR2032 coin type Lithium battery High accuracy without calibration Tolerance to power supply transient drops
