LTC1966 Converter Precision Micropower Delta RMS to DC Convert Module 2.7V~5.5V

Description: The LTC1966 is a true RMS-to-DC converter Module. The internal delta-sigma circuitry to use,more accurate, lower power and dramatically more flexible than conventional log-antilog RMS-to-DCconverl ers. The LTC1966 accepts single ended or differential inputsignals (for EM/RFI rejection) and supports crest factors up to 4. Common mode input range is rail-to-rail. Differ-ential input range is 1VpEAK, and offers unprecedented lin-earity. Unlike previouslyavailable RMS-to-DCconverters, the superior linearity of the LTC1966 allows hassle-free system calibration at any input voltage. The LTC1966 also has a rail-to-rail output with a separateoutput reference pin providing flexible levei shitting. The LTC1966 operates on a single power supply from 2.7V to 5.5V or dual supplies up to ¡À5.5V. Alow power shut down mode reduces supply current to 0.5uA. The LTC1966 is insensitive to PC board soldering andstresses, as well as operating temperature. Features: No-Hassle Simplicity: True RMS-DC Conversion with Only One External Capacitor High Accuracy: 0.1% Gain Accuracy from 50Hz to 1kHz 0.25% Total Error from 50Hz to 1kHz High Linearity: 0.02% Linearity Allows Simple System Calibration Low Supply Current: 155uA Typ,170uA Max Ultralow Shutdown Current: 0.1yA Constant Bandwidth; Independent of Input Voltage 800kHz-3dB, 6kHz ¡À1% Flexible Supplies: 2.7V to 5.5V Single Supply Up to ¡À5.5V Dual Supply Package Included:1 x LTC1966 Precision Micropower RMS to DC Converter Module
