Description
The FAN3850A 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 FAN3850A features an integrated LDO and is
powered from the system supply rails up to 3.63V, with
low power consumption of only 0.85mW and less than
20μW in Power-Down Mode.
Applications
Electret Condenser Microphones with Digital Output
Mobile Handset
Headset Accessories
Personal Computer (PC)
