LPV811/LPV812 Precision Nanopower Op Amps

Texas Instruments LPV811/LPV812 Precision Nanopower Operational Amplifiers are designed for “Always ON” sensing applications in battery-powered wireless and low-power wired equipment. These operational amplifiers come with 8kHz bandwidth from 425nA of quiescent current and a trimmed offset voltage to under 300µV. These LPV81x amplifiers provide 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 ultra-low-power, the Texas Instruments LPV81x amplifiers have CMOS input stages with fempto-amp bias currents for impedance source applications. The LPV81x amplifiers also feature a negative-rail sensing input stage and a rail-to-rail output stage that swings within millivolts of the rails, maintaining the widest dynamic range possible. EMI protection is designed into the LPV81x to reduce system sensitivity to unwanted RF signals from mobile phones, WiFi, radio transmitters, and tag readers.
