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 bination of low initial offset, low offset drift, and 8 k Hz of bandwidth from 650 n A 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.
The LPV821 zero-drift operational amplifier uses a proprietary auto-calibration technique to simultaneously provide low offset voltage (10 μV, maximum) and minimal drift over time and temperature. In addition to having low offset and ultra-low quiescent current, the LPV821 amplifier has pico-amp bias currents which reduce errors monly introduced in applications monitoring sensors with high output impedance and amplifier configurations with megaohm feedback resistors.
