DESCRIPTION

The PCM1748 is a CMOS, monolithic, integrated

circuit which includes stereo digital-to-analog con-

verters (DAC) and support circuitry in a small

SSOP-16 package. The data converters use Texas

Instruments' enhanced multilevel delta-sigma archi-

tecture that employs fourth-order noise shaping and

8-level amplitude quantization to achieve excellent

dynamic performance and improved 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 100 kHz are supported. A full

set of user-programmable functions is accessible

through a 3-wire serial-control port that supports

• 0.002%, Typical (PCM1748KE)

• 0.003%, Typical (PCM1748E)

– Full-Scale Output: 3.1 Vp-p, Typical

8× Oversampling Digital Filter:

– Stop-Band Attenuation: –55 dB

– Pass-Band Ripple: ±0.03 dB

Sampling Frequency: 5 kHz to 100 kHz

•

System Clock: 256 f_S, 384 f_S, 512 f_S, 768 f_S

With Autodetect

•

Accepts 16-, 18-, 20-, and 24-Bit Audio Data

Data Formats: Standard, I²S, and

Left-Justified

•

User-Programmable Mode Controls:

– Digital Attenuation: 0 dB to –63 dB,

0.5 dB/Step

– Digital De-Emphasis

– Digital Filter Rolloff: Sharp or Slow

– Soft Mute

– Zero Flags for Each Output

Dual-Supply Operation:

– 5-V Analog

•

– 3.3-V Digital

•

5-V Tolerant Digital Inputs

Small SSOP-16 Package
