DESCRIPTION

The PCM1742 is a CMOS, monolithic, integrated circuit

which includes stereo Digital-to-Analog Converters

(DACs) and support circuitry in a small SSOP-16 package.

The data converters utilize Texas Instrument’s enhanced

multilevel delta-sigma architecture that employs fourth-

order noise shaping and 8-level amplitude quantization to

achieve excellent dynamic performance and improved toler-

ance to clock jitter. The PCM1742 accepts industry standard

audio data formats with 16- to 24-bit data, providing easy

interfacing to audio DSP and decoder chips. Sampling rates

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

mable functions are accessible through a 3-wire serial

control port that supports register write functions.

●

ACCEPTS 16-, 18-, 20-, AND 24-BIT AUDIO

DATA

DATA FORMATS: Standard, I²S, and Left-

Justified

● USER-PROGRAMMABLE MODE CONTROLS:

Digital Attenuation: 0dB to –63dB, 0.5dB/Step

Digital De-Emphasis

Digital Filter Roll-Off: Sharp or Slow

Soft Mute

Zero Flags for Each Output

●

DUAL-SUPPLY OPERATION:

+5V Analog, +3.3V Digital
