PCM4220PFB

The PCM4220PFB is a 123dB SNR stereo audio Analogue to Digital Converter with PCM output provides 24-bit linear PCM output data, with support for output word length reduction to 24-bits. The PCM4220 includes three sampling modes, supporting output sampling rates from 8kHz to 216kHz. The PCM4220 is ideal for a variety of digital audio recording and processing applications. A linear phase digital decimation filtering engine supports classic and low group delay filter responses, allowing optimization for either studio or live sound applications. In addition, digital high-pass filtering is provided for DC offset removal. The PCM4220 is configured using dedicated control pins for selection of sampling modes, audio data formats and word length, decimation filter response, high-pass filter disable and reset/power-down functions.
