DESCRIPTION

PCM Data Formats: Standard, I S, and

The PCM1791A is a monolithic CMOS integrated circuit

that includes stereo digital-to-analog converters and

support circuitry in a small 28-lead SSOP package. The

data converters use TI’s advanced segment DAC

architecture to achieve excellent dynamic performance

and improved tolerance to clock jitter. The PCM1791A

provides balanced voltage outputs, allowing the user to

optimize analog performance externally. The PCM1791A

accepts PCM and DSD audio data formats, providing easy

interfacing to audio DSP and decoder chips. The

PCM1791A also accepts interface to external digital filter

devices (DF1704, DF1706, PMD200). Sampling rates up

to 200 kHz are supported. A full set of user-programmable

functions is accessible through an SPI or I²C serial control

port, which supports register write and readback functions.

The PCM1791A also supports the time-division-

multiplexed command and audio (TDMCA) data format.

DSD Format Interface Available

Optional Interface to External Digital Filter or

DSP Available

TDMCA or Serial Port (SPI/I C)

User-Programmable Mode Controls:

− Digital Attenuation: 0 dB to –120 dB,

0.5 dB/Step

− Digital De-Emphasis

− Digital Filter Rolloff: Sharp or Slow

− Soft Mute

− Zero Flag for Each Output/PCM and DSD

Formats

Dual Supply Operation:

− 5-V Analog, 3.3-V Digital

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.
