64-lead LQFP

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
