Precision nanopower operational amplifiers maximizes battery and sensor life

Texas Instruments has introduced what is claimed to be the industry’s first precision nanopower operational amplifiers (op amps). The LPV811 and LPV812 consume quiescent current as low as 320nA 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 300µV, the new family of op amps extends battery and sensor life for applications such as building automation, wired and wireless sensor nodes, and wearables. In addition, the LPV811 family of amplifiers can drive the ADS7042 successive approximation register (SAR) analog-to-digital converter, helping to deliver an ultra-low-power analog front end.
