DESCRIPTION

PCM Data Formats: Standard, I S, and

The PCM1794A 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 PCM1794A

provides balanced current outputs, allowing the user to

optimize analog performance externally. Sampling rates

up to 200 kHz are supported.

Optional Interface Available to External

Digital Filter or DSP

Digital De-Emphasis

Digital Filter Rolloff: Sharp or Slow

Soft Mute

Zero Flag

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.
