DESCRIPTION

The PCM1796 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 PCM1796 provides balanced

current outputs, allowing the user to optimize analog

performance externally. The PCM1796 accepts PCM and

DSD audio data formats, providing easy interfacing to

audio DSP and decoder chips. The PCM1796 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

PCM1796 also supports the time division multiplexed

command and audio (TDMCA) data format.

DSD Format Interface Available

Interface Available for Optional External

Digital Filter or DSP

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

Compatible With PCM1792 (Pins and Mode

Controls)

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.
