GENERAL DESCRIPTION
The AD1934 is a high performance, single chip that provides
eight digital-to-analog converters (DACs) with single-ended
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 AD1934 operates from 3.3 V digital and analog supplies.
The AD1934 is available in a 48-lead (single-ended output)
LQFP. Other members of this family include a differential DAC
output version.
The AD1934 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 AD1934 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.
