APPLICATIONS

DESCRIPTION

The DSD1794A 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 DSD1794A

provides balanced current outputs, allowing the user to

optimize analog performance externally. The DSD1794A

accepts the PCM and DSD audio data formats, providing

easy interfacing to audio DSP and decoder chips. The

DSD1794A also interfaces with external digital filter

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

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

port.

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
