650nA High Precision Nano Power Zero Drift Amplifier 'LPV821'
The LPV821 is designed for "always-on" sensing applications in wireless/wired devices that require low input offset. With low initial offset, low offset drift, an 8kHz bandwidth, and a quiescent current of 650nA, it is suitable for end devices that monitor current consumption, temperature, gas, and strain gauges. Utilizing a unique auto-calibration feature, it provides low offset voltage (up to 20µV) and minimal drift across all time and temperature ranges. In addition to low offset and ultra-low quiescent current, the ultra-low bias current in the picoampere range reduces errors typically encountered in sensor monitoring applications with high output impedance and amplifier configurations that include megaohm feedback resistors. It also features an input stage with a rail-to-rail common mode range and an output stage that swings within 15mV of the rails, maintaining a wide dynamic range. Enhanced EMI characteristics reduce the system's sensitivity to unwanted RF signals from mobile phones, WiFi, wireless transmitters, and tag readers. *For more details, please contact us.*
