PCM3003

The PCM3002 and PCM3003 are low cost single chip stereo audio CODECs (analog-to-digital and digital-toanalog converters) with single-ended analog voltage input and output.

The ADCs and DACs PCM3003 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.

PCM3002's programmable functions are controlled by software and the PCM3003's functions include deemphasis, power down, and audio data format selections, which are controlled by hardware.
