LPV542DNXT Datasheet PDF - TI

●The LPV542DNXT is a dual nanopower Operational Amplifier provides 8kHz of bandwidth from 490nA of quiescent current making it well suited for battery-powered applications such as health and fitness wearables, building automation and remote sensing nodes. Each amplifier has a CMOS input stage with pico-amp bias currents which reduces errors commonly introduced in megaohm feedback resistance topologies such as photodiode and charge sense applications. In addition, the input common-mode range extends to the power supply rails and the output swings to within 3mV of the rails, maintaining the widest dynamic range possible. Likewise, EMI protection is designed into the LPV542 in order to reduce system sensitivity to unwanted RF signals from mobile phones, WiFi, radio transmitters and tag readers. The LPV542 operates on a supply voltage as low as 1.6V, ensuring continuous superior performance in low battery situations.
