AD1939

GENERAL DESCRIPTION

The

AD1939

is a high performance, single-chip codec that

provides four analog-to-digital converters (ADCs) with

differential input, and eight digital-to-analog converters (DACs)

with differential output using the Analog Devices, Inc. patented

multibit sigma-delta (Σ-Δ) architecture. An SPI port is included,

allowing a microcontroller to adjust volume and many other

parameters. The

AD1939

operates from 3.3 V digital and analog

supplies. The

AD1939

is available in a 64-lead (differential

output) LQFP package.

The

AD1939

is designed for low EMI. This consideration is

apparent in both the system and circuit design architectures.

By using the on-board PLL to derive the master clock from the

LR clock or from an external crystal, the

AD1939

eliminates

the need for a separate high frequency master clock and can

also be used with a suppressed bit clock. The DACs and ADCs

are designed using the latest Analog Devices continuous time

architectures to further minimize EMI. By using 3.3 V supplies,

power consumption is minimized, further reducing emissions.

APPLICATIONS

Automotive audio systems

Home Theater Systems

Set-top boxes

Digital audio effects processors
