STMicroelectronics TSU111IY
The TSU111IY and TSU112IY operational amplifiers (op-amp) offer an ultra lowpower consumption per channel of 920 nA typical and 1.3 µA maximum when supplied by 3.3 V. The high accuracy of 150 µV max. Combined with a supply voltage range of 1.5 V to 5.5 V, these features allow the TSU111IY and TSU112IY to be efficiently supplied by a coin type Lithium battery or a regulated voltage in low-power applications.| Part No. | TSU111IY |
