The FAN3850T integrates a pre-amplifier, LDO, and Analog-to-Digital Converter (ADC) to convert Electret Condenser Microphone (ECM) outputs to digital Pulse Density Modulation (PDM) data streams. The pre-amplifier accepts analog signals from the ECM and drives an over-sampled sigma delta ADC and outputs PDM data. The PDM digital audio has the advantage of noise rejection and interface-to-mobile handset processors.The FAN3850T is powered from the system supply rails up to 3.63V, with a low power consumption of only 0.85mW, and less than 20µW in Power-Down Mode. The device compensates for the temperature variation of the microphone element to achieve a flat sensitivity response over-temperature.
