FAN3852 pre-amplifier equivalent, microphone pre-amplifier.
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.
Features
* Accepts Input from Electret Condenser Microphones (ECM)
* Pulse Density Modulation (PDM) Output
* Standard.
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 si.
