| Abstract: FL 201 Digital Microphone IC Fortemedia's FL201 FL201 is a digital microphone IC for both MEMS and ECM digital microphones. The Delta-Sigma ADC converts the sensor's output signal into a PDM formatted bit-stream. The digital output format saves the AC coupled capacitor, reduces the RF noise, and eases layout requirements. FL201 FL201 can be used to either for dual microphone array or stereo microphone applications using a , VPUMP VDD GND CS Enhance DATA CLK Dir Description I O P G I I O I Microphone input Charge pump output ... | Original |
