The PCM1748 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 im-

proved tolerance to clock jitter. The PCM1748 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

100kHz are supported. A full set of user-programmable functions

are accessible through a 3-wire serial control port that supports

●

SAMPLING FREQUENCY: 5kHz to 100kHz

SYSTEM CLOCK: 256, 384, 512, 768f_Swith

Auto Detect

●

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

DATAzx

DATA FORMATS: Standard, I²S, and

Left-Justified

● USER-PROGRAMMABLE MODE CONTROLS:

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