AS3501 AS3502 Data Sheet Low Power Ambient Noise-Cancelling Speaker Driver 1 General Description The AS3501/02 are speaker driver with Ambient Noise Cancelling function for headsets, headphones or ear pieces. It is intended to improve quality of e.g. music listening, a phone conversation etc. by reducing background ambient noise. The fully analog implementation allows the lowest power consumption, lowest system BOM cost and most natural received voice enhancement otherwise difficult to achieve with DSP implementations. The device is designed to be easily applied to existing architectures. An internal OTP-ROM can be optionally used to store the microphones gain calibration settings.
