The ADCs and DACs employ delta-sigma modulation with 64X oversampling. The ADCs include a digital decimation filter, and the DACs include an 8X oversampling digital interpolation filter. The DACs also include digital attenuation, de-emphasis, infinite zero detection and soft mute to form a complete subsystem. PCM3002 and PCM3003 operate with left-justified, and right-justified formats, while the PCM3002 also supports the I2S data format. PCM3002 and PCM3003 provide a power-down mode that operates on the ADCs and DACs independently. Fabricated on a highly advanced CMOS process, PCM3002 and PCM3003 are suitable for a wide variety of cost-sensitive consumer applications where good performance is required.
