1 / 32 page  Features • AEC-Q101 qualified • Sub-micro ampere current consumption: Icc = 920 nA typ. at 25 °C • Low offset voltage: 150 µV max. at 25 °C, 400 µV max. over full temperature range (-40 to 125 °C) • Low noise over 0.1 to 10 Hz bandwidth: 4.6 µVpp • Low supply voltage: 1.5 V to 5.5 V • Rail-to-rail input and output • Gain bandwidth product: 9 kHz typ. • Low input bias current: 10 pA max. at 25 °C • High tolerance to ESD: 4 kV HBM • More than 25 years of typical equivalent lifetime supplied by a 220 mA.h CR2032 coin type Lithium battery • High accuracy without calibration • Tolerance to power supply transient drops Applications • 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 Description The 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. The high accuracy of 150 µV max. and 9 kHz gain bandwidth make the TSU112IY ideal for sensor signal conditioning, battery management system, on-board (OBC) and wireless chargers.
