LTC1966 Converter Precision Micro Power RMS to DC Converter Module

Feature: The LTC1966 is a True RMS to DC converter that uses the innovative patented calculation technology. The LTC1966's internal incremental-to-accumulate () 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. Parameter: 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: 155A (typ.) 170A (max) Ultra-low shutdown current: 0.1A Constant bandwidth: independent of input voltage 800kHz -3dB, 6kHz 1% Flexible power supply: 2.7V to 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 C to 125 C Pin Description: VCC: Positive power supply 2.7V to 5.5V VSS: Supply negative GND to 5.5V IN1, IN2: differential input OUT: Conversion voltage output EN: Input enable control terminal, active low, the circuit is connected to the low level by default. Package includes: 1 x Converter
