The first operational amplifier (op amp) to combine ultra high precision with what the company claims to be the industry’s lowest supply current has been announced by Texas Instruments. With power-to-precision performance, the LPV821 zero-drift, nanopower op amp enables engineers to attain the highest DC precision, while consuming 60% 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 life times.
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 programme a threshold that will automatically wake up a MicroController (MCU) such as the CC1310 SimpleLink Sub-1GHz MCU, further reducing system power consumption.
