The from Texas Instruments is a dual channel precision 425nA nanopower operational amplifier in 8 pin VSSOP package. This is an ultralow power precision operational amplifier family for "Always ON" sensing applications in battery powered wireless and low power wired equipment. With 8KHz of bandwidth from 425nA of quiescent current and a trimmed offset voltage to under 300µV, the amplifier provides the required precision while minimizing power consumption in equipment such as gas detectors and portable electronic devices where operational battery-life is critical. In addition to being ultra-low-power, amplifier has CMOS input stages with fempto-amp bias currents for impedance source applications. It is used in CO and O2 das detectors DA-0756, PIR motion detectors, current sensing, thermostats, IoT remote sensors and active RFID readers and tags.
