DESCRIPTION

768 f With Autodetect

Accepts 16-, 20-, and 24-Bit Audio Data

The PCM1792A 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 PCM1792A

provides balanced current outputs, allowing the user to

optimize analog performance externally. The PCM1792A

accepts PCM and DSD audio data formats, providing easy

interfacing to audio DSP and decoder chips. The

PCM1792A also interfaces with 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 PCM1792A also supports the time division

multiplexed command and audio (TDMCA) data format.

PCM Data Formats: Standard, I S, and

Left-Justified

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

Dual Supply Operation:

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.
