Description
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 calibrationLow supply current: 155?A (typ.), 170?A (max)Ultra-low shutdown current: 0.1?AConstant bandwidth: independent of input voltage 800kHz -3dB, 6kHz ± 1%Flexible power supply: 2.7V to 5.5V single supply, dual supply up to ±5.5VFlexible inputs: differential or single-ended rail-to-rail common-mode voltage range, up to 1VPEAK differential voltageFlexible output: rail-to-rail output, separate output reference pins provide level shiftingWide temperature range: -55 ° C to 125 ° C Pin Description: VCC: Positive power supply 2.7V to 5.5VVSS: Supply negative GND to 5.5VIN1, IN2: differential inputOUT: Conversion voltage outputEN: Input enable control terminal, active low, the circuit is connected to the low level by default.Package includes:
