APPLICATIONS

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-to-

analog

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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible

to damage because very small parametric changes could cause the device not to meet its published specifications.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
