GENERAL DESCRIPTION

Optimized for direct digital synthesis (DDS) waveform recon-

struction, the AD9731 provides 50 dB of wideband harmonic

suppression over a dc-to-65 MHz analog output bandwidth.

This signal bandwidth addresses the transmit spectrum in many

of the emerging digital communications applications where

signal purity is critical. Narrowband, the AD9731 provides an

SFDR of greater than 79 dB. This excellent wideband and

narrowband ac performance, coupled with a lower pricing struc-

ture, make the AD9731 the optimum high performance DAC

value.

The AD9731 is a 10-bit, 170 MSPS, bipolar D/A converter that

is optimized to provide high dynamic performance, yet offer

lower power dissipation and more economical pricing than

afforded by previous bipolar high performance DAC solutions.

The AD9731 was designed primarily for demanding communi-

cations systems applications where wideband spurious-free

dynamic range (SFDR) requirements are strenuous and could

previously only be met by using a high performance DAC such

as the industry-standard AD9721. The proliferation of digital

communications into basestation and high volume subscriber-

end markets has created a demand for excellent DAC perfor-

mance delivered at reduced levels of power dissipation and cost.

The AD9731 is the answer to that demand.

The AD9731 is packaged in 28-lead SOIC (same footprint

as the industry standard AD9721) and super space-saving

28-lead SSOP; both are specified to operate over the extended

industrial temperature range of –40°C to +85°C.
