DESCRIPTION
The PCM3006 is a low-cost, single-chip stereo audio
codec (analog-to-digital and digital-to-analog con-
verters) with single-ended analog voltage input and
output.
Both ADCs and DACs employ delta-sigma modu-
lation 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.
