TI unveils nanopower operational amplifiers

Texas Instruments (TI) has introduced first precision nanopower operational amplifiers (op amps). The LPV811 and LPV812 consume quiescent current of 320 nA and are part of a family of four 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 ÁV, the company claims.

The new family of op amps extends battery and sensor life for applications such as building automation, wired and wireless sensor nodes, and wearables.

Some of the key features and benefits of the LPV811 family are mentioned below:

These nanopower op amps enable more energy-efficient 4- to 20-mA loop systems.

By having an offset voltage specification of 300 ÁV, LPV811 and LPV812 can be used to detect environmental gases even in lower concentrations and also enhance the life of truly electrochemical sensors.

The general purpose LPV801 and LPV802 and precision LPV811 and LPV812 can be operated from a supply voltage of even down to 1.6 V allowing to power the unit using low-voltage batteries.

When it comes to noise specifications by having an input rejection ratio greater than 80 dB in the 500-MHz to 1-GHz frequency these op amps allow design engineers to save from using external filtering components.

The LPV811 can drive ADS7042 successive approximation register (SAR) analog-to-digital converter directly.
