TI delivers the most precise nanopower op amp, reducing system power and maximizing battery life in precision IoT, industrial and personal electronics applications
Texas Instruments (TI) introduced the first operational amplifier (op amp) 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.
The LPV821 op amp is the newest device in TI's low-power amplifier portfolio, which enables engineers to design lighter, smaller and more portable applications with lower-capacity batteries and longer system lifetimes.
Key features and benefits of the LPV821 op amp
Engineers can pair the LPV821 op amp with the TLV3691 nanopower comparator or ADS7142 nanopower analog-to-digital converter (ADC) to program a threshold that will automatically wake up a microcontroller (MCU) such as the CC1310 SimpleLink™ Sub-1 GHz MCU, further reducing system power consumption.
Tools and support to speed design
Designers can download the TINA-TI™ SPICE model to simulate their designs and predict circuit behavior when using the LPV821 op amp. Engineers can also jump-start gas-sensing system designs using the LPV821 op amp with the Always-On Low-Power Gas Sensing with 10+ Year Coin Cell Battery Life Reference Design and Micropower Electrochemical Gas Sensor Amplifier Reference Design.
Package, availability and pricing
Pre-production samples of the LPV821 op amp are now available through the TI store and authorized distributors in a 5-pin small-outline transistor (SOT-23) package. Pricing starts at US$0.80 in 1,000-unit quantities.
