FAN3850T Datasheet (Fairchild Semiconductor)

FAN3850T, Microphone Pre-Amplifier

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 outpu
