Descriptions
Descriptions of onsemi FAN3850AUC19X provided by its distributors.
8542.33.00.01 FAN3850 Tape & Reel (TR) ADC Microphone audio amplifier 4V 197mum 470muA 62dB
Audio Amp Microphone 1-CH Mono Class-AB 6-Pin WLCSP T/R
Microphone Pre-Amplifier with Digital Output
Audio Preamplifier, CMOS, PBGA6
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.
