3 Description
The LPV801 (single) and LPV802 (dual) comprise a
family of ultra-low-power operational amplifiers for
sensing applications in battery powered wireless and
low power wired equipment. With 8kHz of bandwidth
from 320nA of quiescent current, the LPV80x
amplifiers minimize power consumption in equipment
such as CO detectors, smoke detectors and PIR
motion detectors where operational battery-life is
critical.
In addition to being ultra-low-power, the LPV80x
amplifiers have CMOS input stages with typically
femto-amp bias currents. The LPV80x amplifiers also
feature a negative-rail sensing input stage and a railto-
rail output stage that is capable of swinging within
millivolts of the rails, maintaining the widest dynamic
range possible. EMI protection is designed into the
LPV80x in order to reduce system sensitivity to
unwanted RF signals from mobile phones, WiFi, radio
transmitters and tag readers.
