LTC1966 Accurate Micropower Module for Delta Sigma RMS to DC Converter Breakout Board Module

The LTC1966 is a True RMS to DC converter that uses the innovative patented ΔΣ calculation technology. The LTC1966's internal incremental-to-accumulate (ΔΣ) circuit makes it simpler to use, and is more accurate, less powerful, and more flexible than traditional logarithmic anti-log RMS to DC converters.

The LTC1966 accepts single-ended or differential input signals (to suppress EMI / RFI) and supports crest factors up to 4. Unlike previous RMS to DC converters, the LTC1966's excellent linearity enables easy system calibration at any input voltage.

High accuracy: 0.1% gain accuracy (from 50Hz to 1kHz), 0.25% total error (from 50Hz to 1kHz)

High linearity: 0.02% linearity for simple system calibration

Low supply current: 155μA (typ), 170μA (max)

Ultra-low shutdown current: 0.1μA

Constant bandwidth: independent of input voltage 800kHz -3dB, 6kHz ± 1%

Flexible power supply: 2.7V -5.5V single supply, dual supply up to ±5.5V

Flexible inputs: differential or single-ended rail-to-rail common-mode voltage range, up to 1VPEAK differential voltage

Flexible output: rail-to-rail output, separate output reference pins provide level shifting

Wide temperature range: -55 -125°C
