3 Description
The LPV811 (single) and LPV812 (dual) are a ultralow-
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.
