GENERAL DESCRIPTION
The AD1933 is a high performance, single chip that provides
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 AD1933 operates from 3.3 V digital and analog supplies.
The AD1933 is available in a 64-lead (differential output) LQFP.
Other members of this family include a single-ended DAC
output version.
The AD1933 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 AD1933 eliminates the
need for a separate high frequency master clock and can also be
used with a suppressed bit clock. The DACs 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.
