The TSU111, TSU112 and the TSU114 operational amplifiers (op-amp) offer an ultra low-power consumption per channel of 900 nA typical and 1.2 µA maximum when supplied by 3.3 V. Combined with a supply voltage range of 1.5 V to 5.5 V, these features allow the TSU11x to be efficiently supplied by a coin type Lithium battery or a regulated voltage in low-power applications.


The high accuracy of 150 µV max. and 11.5 kHz gain bandwidth make the TSU11x ideal for sensor signal conditioning, battery supplied, and portable applications.
