Overview
The LPV801DBVR is a single-channel, ultra-low power operational amplifier manufactured by Texas Instruments. Designed for battery-powered and energy-harvested applications, this nanoPower CMOS operational amplifier operates on a single supply voltage as low as 1.6V. Its rail-to-rail output and extended common-mode range make it ideal for single-supply applications. The LPV801DBVR is housed in a compact SOT-23 package, making it suitable for space-constrained designs. It is particularly targeted at applications requiring long battery life, such as gas detectors, smoke alarms, and motion sensors.
