DESCRIPTION

•

Zero Flags for Selectable Channel

Combinations

The PCM1680 is a CMOS monolithic integrated

circuit which features eight 24-bit audio digi-

tal-to-analog converters and support circuitry in a

small 28-lead SSOP. The digital-to-analog converters

use TI's enhanced multilevel delta-sigma architecture

to achieve excellent signal-to-noise performance and

a high tolerance to clock jitter.

•

Serial Port (SPI/I²C) for Mode Control

User-Programmable Functions:

– Flexible Audio Data Formats

• Right-Justified, I²S, and Left-Justified

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

– Digital Attenuation: Mode Selectable

• 0 dB to –63 dB, 0.5 dB/step

• 0 dB to –100 dB, 1 dB/step

– Soft Mute

The PCM1680 accepts industry-standard audio data

formats with 16- to 24-bit audio data. Sampling rates

up to 200 kHz are supported. The PCM1680 provides

a full set of user-programmable functions through a

serial control port, SPI or I²C.

– Digital De-Emphasis

– Digital Filter Rolloff: Sharp or Slow
