LTC1966 Converter Precision Micro Power RMS to DC Converter Module

Feature The LTC1966 is a True RMS to DC converter that uses the innovative patentedcalculation technology The LTC1966s 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 LTC1966s 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 155A typ 170A max Ultra low shutdown current 0 1AConstant bandwidth independent of input voltage 800kHz 3dB 6kHz1 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 55C to 125C 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 1 x Converter
