The DAC2904 combines high dynamic performance with a

high update rate to create a cost-effective solution for a wide

variety of waveform-synthesis applications:

DESCRIPTION

The DAC2904 is a monolithic, 14-bit, dual-channel,

high-speed Digital-to-Analog Converter (DAC), and is opti-

mized to provide high dynamic performance while dissipating

only 310mW.

• Pin compatibility between family members provides 10-bit

(DAC2900), 12-bit (DAC2902), and 14-bit (DAC2904)

resolution.

Operating with high update rates of up to 125MSPS, the

DAC2904 offers exceptional dynamic performance, and

enables the generation of very-high output frequencies suit-

able for “Direct IF” applications. The DAC2904 has been

optimized for communications applications in which sepa-

rate I and Q data are processed while maintaining tight-gain

and offset matching.

• Pin compatible to the AD9767 dual DAC.

• Gain matching is typically 0.5% of full-scale, and offset

matching is specified at 0.02% max.

• The DAC2904 utilizes an advanced CMOS process; the

segmented architecture minimizes output-glitch energy,

and maximizes the dynamic performance.

• All digital inputs are +3.3V and +5V logic compatible. The

DAC2904 has an internal reference circuit, and allows use

in a multiplying configuration.

Each DAC has a high-impedance differential-current output,

suitable for single-ended or differential analog-output con-

figurations.

• The DAC2904 is available in a TQFP-48 package, and is

specified over the extended industrial temperature range of

–40°C to +85°C.
