General Description

The LPV542 is an ultra-low-power, dual operational amplifier that provides 8kHz of bandwidth from 490nA of quiescent current making it well suited for batterypowered applications such as health and fitness wearables, building automation, and remote sensing nodes.

Each amplifier has a CMOS input stage with picoamp bias currents which reduces errors monly introduced in megaohm feedback resistance topologies such as photodiode and charge sense applications.

In addition, the input mon-mode range extends to the power supply rails and the output swings to within 3 mV of the rails, maintaining the widest dynamic range possible.

Key Features
