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...
