DESCRIPTION

The PCM1742 is a CMOS, monolithic, integrated

circuit which includes stereo digital-to-analog con-

verters (DACs) 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 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 200 kHz are supported. A full

set of user-programmable functions is accessible

through a 3-wire serial control port that supports

• 0.002%, Typical (PCM1742KE)

• 0.003%, Typical (PCM1742E)

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

•

4x/8x Oversampling Digital Filter:

Stop-Band Attenuation: –55 dB

Pass-Band Ripple: ±0.03 dB

•

Sampling Frequency: 5 kHz to 200 kHz

System Clock: 128 f_S, 192 f_S, 256 f_S, 384 f_S,

512 f_S, 768 f_SWith 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
