1 / 8 page New Products, Tips and Tools for Power and Mobile Applications BENCHMarks™ Digital Microphones Improve Sound Quality, Lower Power Achieve better sound quality in mobile handset and notebook microphone applications with Fairchild’s FAN3850x series of digital microphone pre-amplifiers. These high performance analog mobile audio devices provide advanced noise rejection capabilities as well as an easy interface to mobile handset processors. The series includes: • FAN3850A that features both 16dB and 19dB gain versions, • FAN3850T offering 15dB gain and integrated negative temperature coefficient to compensate for ECM positive temperature coefficient to achieve a flat sensitivity response over temperature. Both devices integrate a pre-amplifier, low drop-out regulator (LDO) and analog- to-digital converter (ADC) that converts Electret Condenser Microphone (ECM) outputs to digital pulse density modulation (PDM) data streams. Advantages • Excellentsignal-to-noiseratio • Lowerpowercompensation, 0.8mW • <20μWpowerdownmode Applications • Mobilehandsets • NotebookPCmicrophones For more information, please visit: www.fairchildsemi.com/pf/FA/FAN3850A.html www.fairchildsemi.com/pf/FA/FAN3850T.html VOL. 1, 2012 90 0.001 0.01 0.1 1 Input Signal (mVpp) SNR (dBa) THD (dB) SINAD (dB) 10 100 80 70 60 50 40 30 20 10 0 -10 -20 FAN3850T 15dB SNR (dBa), THD (-dB), SINAD (dB) over Input Amplitude Product Number I DD (μA) I SLEEP (μA) SNR (dB) THD (%) 120dB SPL THD + N (%) ESD (HBM) (kV) FAN3850x 420 1.4 62 0.01 3 7 V DD = 1.8V, FCLOCK = 2.4MHz, 94dBSPL |
