Audio Codec 2ADC / 2DAC 16-Bit 24-Pin SSOP Tube

The PCM3006 is a low-cost, single-chip stereo audio codec (analog-to-digital and digital-to-analog converters) with single-ended analog voltage input and output. Both ADCs and DACs employ delta-sigma modulation with 64-times oversampling. The ADCs include a digital decimation filter, and the DACs include an 8-times oversampling digital interpolation filter. The DACs also include a digital de-emphasis function. The PCM3006 operates with 16-bit, left-justified for ADC, right-justified for DAC data formats. The PCM3006 provides a power-down mode that operates on the ADCs and DACs independently. The PCM3006 is fabricated using a highly advanced CMOS process, and is available in a small 24-pin TSSOP package. The PCM3006 is suitable for a wide variety of cost-sensitive consumer applications where good performance is required.
