STMicroelectronics TSU112IY Nanopower High Accuracy Op Amp

STMicroelectronics TSU112IY Nanopower High Accuracy Op Amp

STMicroelectronics TSU112IY Nanopower High Accuracy Operational Amplifier (Op-Amp) offers an ultra low-power consumption per channel of 920nA typical and 1.3µA maximum when supplied by 3.3V. Combined with a supply voltage range of 1.5V to 5.5V, these features allow the TSU112IY to be efficiently supplied by a coin-type Lithium battery or a regulated voltage in low-power applications. The high accuracy of 150µV (max.) and 9kHz gain bandwidth make the STMicroelectronics TSU112IY ideal for sensor signal conditioning, battery management system, onboard (OBC), and wireless chargers.
