Texas Instruments (TI) today introduced the industry’s first precision
nanopower operational amplifiers (op amps). The LPV811 and LPV812
consume quiescent current as low as 320 nA and are a part of a family of 4
new ultra-low-power op amps. With up to 60 percent lower power
consumption than competitive precision op amps and offset voltage as low
as 300 µV, the new family of op amps extends battery and sensor life
for applications like building automation, wired and wireless sensor nodes, and wearables.
Key features and benefits of the LPV811 family
Low power consumption: Featuring industry-leading quiescent current without the utilization of duty cycling, these nanopower op amps enable more energy-efficient 4- to 20-mA loop systems, extend battery life and reduce battery replacement costs.
High precision: With a precision offset voltage as low as 300 µV and nanopower current consumption, the LPV811 and LPV812 help detect low concentrations of environmental gases and increase two-lead electrochemical sensor life and sensitivity.
Low-voltage operation: Operating with a single-supply voltage as low as 1.6 V, the general-purpose LPV801 and LPV802 and precision LPV811 and LPV812 maintain continuous performance under low-voltage battery conditions.
High electromagnetic interference (EMI) immunity: An input rejection ratio greater than 80 dB within the 500-MHz to 1-GHz frequency range reduces the necessity for external filtering components, saves design time for EMI-sensitive applications and enables rapid system qualification consistent with international standards organizations.
In addition, the LPV811 family of amplifiers can drive the ADS7042 successive approximation register (SAR) digitizer , helping to deliver an ultra-low-power analog front .
To see an indication of the LPV811 precision nanopower op amp family and study other TI industrial and automotive innovations, visit Booth 219 in Hall A4 at the electronica Trade Fair in Munich, now through Nov. 11.
Tools and support to jump-start design
The Low Power carbon monoxide gas gas Sensor with 10+ Year Coin Cell Battery Life reference design demonstrates how the LPV811 nanopower op amp and therefore the CC2650 SimpleLink™ multi-standard wireless microcontroller (MCU) reduce power consumption and extend the battery lifetime of carbon monoxide gas detectors to as long as 10 years and extend their sensing range up to 1,000 parts per million. Designers even have access to a full suite of online support resources, including an entire library of TI Designs and SPICE models.
