Microphone Pre-Amplifier with Digital Output FAN3852 Description The FAN3852 integrates a pre−amplifier, LDO, and ADC that converts 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 Analog−to−Digital Converter (ADC) and outputs PDM data. The PDM digital audio has the advantage of noise rejection and easy interface to mobile handset processors. The FAN3852 features an integrated LDO and is powered from the system supply rails up to 3.63 V, with low power consumption of only 0.85 mW and less than 20 mW in Power−Down Mode.
