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.
