GENERAL DESCRIPTION
The AD1937 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 I2C port is included, allowing a
microcontroller to adjust volume and many other parameters.
The AD1937 operates from 3.3 V digital and analog supplies.
The AD1937 is available in a 64-lead (differential output) LQFP.
The AD1937 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 (frame) clock or from an external crystal, the AD1937 elimi-
nates 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 architecture to further minimize EMI. By using 3.3 V
supplies, power consumption is minimized and further
reduces emissions.
