The LPV821 is a single-channel, nanopower, zero-drift 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.
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 commonly introduced in applications monitoring sensors with high output impedance and amplifier configurations with megaohm feedback resistors.
The LPV821 amplifier also features an input stage with rail-to-rail input common mode range and an output stage that swings within 12 mV of the rails, maintaining the widest dynamic range possible. The device is EMI hardened to reduce system sensitivity to unwanted RF signals from mobile phones, WiFi, radio transmitters, and tag readers.
The LPV821 zero-drift amplifier operates with a single supply voltage as low as 1.7V, ensuring continuous performance in low battery situations over the extended temperature range of -40ºC to 125ºC. The LPV821 (single) is available in industry standard 5-pin SOT-23.
