Design LPV821
SNOSD36A – AUGUST 2017 – REVISED DECEMBER 2017 LPV821, 650nA, Precision, Nanopower, Zero-Drift Amplifier
1 Features 3 Description The LPV821 is a single-channel, nanopower, zerodrift operational amplifier for “Always ON” sensing
applications in wireless and wired equipment where
low input offset is required. With the combination of
low initial offset, low offset drift, and 8 kHz of
bandwidth from 650 nA of quiescent current, the
LPV821 is the industry's lowest power zero-drift
amplifier that can be used for end equipment that
monitor current consumption, temperature, gas, or
strain gauges. 1 Quiescent Current: 650 nA
Low Offset Voltage: В±10 ОјV (Maximum)
Offset Voltage Drift: В±0.096 ОјV/В°C (Maximum)
0.1-Hz to 10-Hz Noise: 3.9 ОјVPP
Input Bias Current: В±7 pA
Gain Bandwidth: 8 kHz
Supply Voltage: 1.7 V to 3.6 V …
