TSU111IYCT

TSU111IYCT is an automotive grade, nanopower, high accuracy CMOS operational amplifier. It 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 1.5 V to 5.5 V, these features allow the TSU111IY to be efficiently supplied by a coin type Lithium battery or a regulated voltage in low-power applications. The high accuracy of 150µV maximum and 9KHz gain bandwidth make the TSU111IY ideal for sensor signal conditioning, battery management system, on-board (OBC) and wireless chargers. Applications include battery management system: ultra-low power op-amp detects when battery is charging/discharging and wakes up CPU, on-board chargers, signal conditioning for energy harvesting, wireless chargers.
