Texas Instruments introduced the first operational amplifier to combine ultra-high precision with the industry's lowest supply current. With exceptional power-to-precision performance, the LPV821 zero-drift, nanopower op amp enables engineers to attain the highest DC precision, while consuming 60 percent less power than competitive zero-drift devices. The LPV821 is designed for use in precision applications such as wireless sensing nodes, home and factory automation equipment, and portable electronics.
TI's zero-drift technology delivers a low initial offset of 10 µV and an offset drift of 0.02 µV/°C, eliminating temperature drift and flicker noise, and enabling engineers to attain the highest DC precision and dynamic error correction. Nanopower consumption enables always-on applications such as continuous and blood glucose monitoring, and other electrochemical cell applications. Additionally, the low supply current decreases the external circuitry required to turn the amplifier on and off.
