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.
