TSU111, TSU112, TSU114 Datasheet Nanopower (900 nA), high accuracy (150 V) 5 V CMOS operational amplifier Features Sub-micro ampere current consumption: Icc = 900 nA typ. at 25 C Low offset voltage: 150 V max. at 25 C, 235 V max. over full temperature range (-40 to 85 C) Low noise over 0.1 to 10 Hz bandwidth: 3.6 Vpp Low supply voltage: 1.5 V to 5.5 V Rail-to-rail input and output Gain bandwidth product: 11.5 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 Gas sensors: CO, O , and H S 2 2 Alarms: PIR sensors Signal conditioning for energy harvesting and wearable products Ultra long-life battery-powered applications Battery current sensing Product status link Active RFID tags TSU111, TSU112, TSU114 Description Related products The TSU111, TSU112 and the TSU114 operational amplifiers (op-amp) offer an ultra See TSU101, TSU102, for further and TSU104 power savings low-power consumption per channel of 900 nA typical and 1.2 A maximum when supplied by 3.3 V. Combined with a supply voltage range of 1.5 V to 5.5 V, these See TSZ121, TSZ122, for increased features allow the TSU11x to be efficiently supplied by a coin type Lithium battery or TSZ124 accuracy a regulated voltage in low-power applications. The high accuracy of 150 V max. and 11.5 kHz gain bandwidth make the TSU11x ideal for sensor signal conditioning, battery supplied, and portable applications.
