Precision Nanopower OP AMP Product Announcement
Consumes Low Quiescent Current of 320nA

TI announced the launch of the industry's first precision nanopower operational amplifier products.

Among the four new ultra-low-power operational amplifiers, the LPV811 and LPV812 consume a low quiescent current of 320nA. Additionally, they consume up to 60% less power compared to competitors' precision operational amplifiers and feature a low offset voltage of 300µV. These new products extend battery and sensor usage time in applications such as building automation, wired/wireless sensor nodes, and wearable devices.

As nanopower operational amplifiers, they provide the industry's best quiescent current without using duty cycle switching, enabling energy-efficient 4mA–20mA loop systems to achieve extended battery life and reduced battery replacement costs.

The LPV811 and LPV812, featuring low precision offset voltage of 300µV and nanopower current consumption, can detect low-concentration ambient gases, thereby improving the usage time and sensitivity of 2-lead electrochemical sensors.

The general-purpose LPV801 and LPV802, and precision LPV811 and LPV812 operating at a low single supply voltage of 1.6V maintain consistent performance even under low-voltage battery conditions.

Achieving input rejection ratio of 80dB or higher in the 500MHz–1GHz frequency range reduces the use of external filtering components, shortens design time when developing EMI-sensitive applications, and enables rapid development of systems meeting international standards.

Additionally, the LPV811 product family can drive the ADS7042 SAR (successive approximation register) analog-to-digital converter, enabling implementation of ultra-low-power analog front-end solutions.
