The STMicroelectronics TSU111, TSU112 and the TSU114 series is a Nano power and high-accuracy operational amplifier (op-amp). It offers an ultra low-power consumption per channel of 900 nA typical and 1.2 μA maximum when supplied by 3.3 V. Supply voltage range of 1.5 V to 5.5 V feature allow the TSU11x to be efficiently supplied by a coin type Lithium battery or a regulated voltage in low-power applications. The TSU11x is ideal for sensor signal conditioning, battery supplied, and portable applications.
