DESCRIPTION

768 f With Autodetect

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

The DSD1794 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 DSD1794 provides balanced

current outputs, allowing the user to optimize analog

performance externally. The DSD1794 accepts the PCM

and DSD audio data formats, providing easy interfacing to

audio DSP and decoder chips. The DSD1794 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 I²C-compatible serial port.

PCM Data Formats: Standard, I S, and

Left-Justified

Optional Interface to External Digital Filter or

DSP Available

I C-Compatible Serial Port

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

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.
