Low-power precision op-amps

9 November 2016 Analogue, Mixed Signal, LSI

Texas Instruments introduced new precision nanopower operational amplifiers - the LPV811 and LPV812 – which consume quiescent current as low as 320 nA and are part of a family of four new ultra-low-power op amps. With up to 60% lower power consumption than competitive precision op amps and offset voltage as low as 300 μV, the devices extend battery and sensor life for applications such as building automation, wired and wireless sensor nodes, and wearables.

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. An input rejection ratio greater than 80 dB in the 500 MHz to 1 GHz frequency range reduces the need for external filtering components, saves design time for EMI-sensitive applications and enables rapid system qualification according to international standards organisations.

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.
