The LPV811 (single) and LPV812 (dual) are a ultra-low-power precision operational amplifier family for “Always ON” sensing applications in battery powered wireless and low power wired equipment. With 8 kHz of bandwidth from 425 nA of quiescent current and a trimmed offset voltage to under 300µV, the 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 being ultra-low-power, the 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 in order to reduce system sensitivity to unwanted RF signals from mobile phones, WiFi, radio transmitters, and tag readers.
