The LTC1966CMS8#TRPBF is a precision micropower RMS to DC converter manufactured by Analog Devices. It is a part of the ADI Power Management Specialized - PMIC family of products. It is optimized for battery-powered and other low power applications, delivering exceptional performance at very low quiescent currents of only 40µA in normal mode and 190nA in power-down. It offers ultra-accurate true RMS sensing and conversion of an AC signal to a DC voltage of up to approximately 6V. It is designed to accept input signals with peak amplitudes up to 18V and is ideal for managing noise-prone low level signals from high impedance sensors. It features fast settling time to less than 18µs and high linearity of +/- 0.4%. The device is available in an 8-lead DFN package.
