DESCRIPTION
The PCM3010 is a low-cost single-chip 24-, 16-bit
stereo audio codec (ADC and DAC) with single-ended
analog voltage input and output. Both the
analog-to-digital converters (ADCs) and digital-toanalog
converters (DACs) employ delta-sigma
modulation with 64-times oversampling. The ADCs
include a digital decimation filter with a high-pass filter,
and the DACs include an 8-times-oversampling digital
interpolation filter. The DACs also include a digital
de-emphasis function. The PCM3010 accepts four
different audio data formats for the ADC and DAC. The
PCM3010 provides a power-down mode, which works
on the ADC and DAC simultaneously. The PCM3010 is
suitable for a wide variety of cost-sensitive consumer
applications where good performance is required. The
PCM3010 is fabricated using a highly advanced CMOS
process and is available in a small 24-pin SSOP
package.
