The STMicroelectronics TSU112IY operational amplifier (op-amp) offers an ultra low-power consumption per channel of 920 nA typical and 1.3 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 TSU112IY to be efficiently supplied by a coin type Lithium battery or a regulated voltage in low-power applications.
