PCM4220 www.ti.com............................................................................................................................................. SBAS407C – DECEMBER 2006 – REVISED AUGUST 2009 PRODUCT OVERVIEW The PCM4220 is a two-channel, multi-bit delta-sigma (ΔΣ) A/D converter. The 6-bit output from the delta-sigma modulators is routed to the digital decimation filter, where the output of the filter provides linear PCM data.

PCM4220 SBAS407C – DECEMBER 2006 – REVISED AUGUST 2009............................................................................................................................................. www.ti.com ANALOG INPUTS The PCM4220 includes two analog inputs, referred to as the left and right channels. Each channel includes a pair of differential voltage input pins. The left channel inputs are named VINL– (pin 10) and VINL+ (pin 11), respectively.

PCM4220 SBAS407C – DECEMBER 2006 – REVISED AUGUST 2009............................................................................................................................................. www.ti.com MASTER CLOCK INPUT The PCM4220 requires a master clock for operating the internal logic and modulator circuitry. The master clock is supplied from an external source, connected at the MCKI input (pin 35). Table 1 summarizes the requirements for various operating modes of the PCM4220.

PCM4220 www.ti.com............................................................................................................................................. SBAS407C – DECEMBER 2006 – REVISED AUGUST 2009 PCM OUTPUT AND SAMPLING MODES The PCM4220 supports 24-bit linear PCM output data when the PCMEN input (pin 16) is forced high. The PCM output is disabled when PCMEN is forced low. The 24-bit output data may be dithered to 20-, 18-, or 16-bits using internal word length reduction circuitry.
