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.

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

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.
