FAN3850T  
Microphone Pre-Amplifier with Temperature  
Compensation and Digital Output  
Description  
Features  
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 pre-  
amplifier 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.  
. Optimized for Mobile Handset and Notebook PC  
Microphone Applications  
. Accepts Input from Electret Condenser Microphones  
. Pulse Density Modulation (PDM) Output  
. Standard 5-Wire Digital Interface  
. Amplifier Gain: 15.7dB or 13.7dB  
The FAN3850T is powered from the system supply rails  
up to 3.63V, with a low power consumption of only  
0.85mW, and less than 20μW in Power-Down Mode.  
The device compensates for the temperature variation  
of the microphone element to achieve a flat sensitivity  
response over-temperature.  
. Negative Temperature Coefficient to Compensate for  
ECM Positive Temperature Coefficient  
. Low Input Capacitance, High PSR, 20kHz  
Pre-Amplifier  
. Low-Power, 1.5µA Sleep Mode  
. Typical 420µA Supply Current  
. Signal to Noise Ratio of 62.4dB(A)  
. Total Harmonic Distortion: 0.01%  
. Input Clock Frequency Range of 1-4MHz  
. Integrated Low Drop-Out Regulator (LDO)  
. Small 1.26mm x 0.86mm 6-Ball WLCSP
