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 preamplifier 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.
