DESCRIPTION

The DAC2900 is a monolithic, 10-bit, dual-channel,

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

optimized to provide high dynamic performance while

dissipating only 310mW on a +5V single supply.

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

DAC2900 offers exceptional dynamic performance, and

enables the generation of very high output frequencies

suitable for Direct IF applications. The DAC2900 has

been optimized for communications applications in which

separate I and Q data are processed while maintaining

tight gain and offset matching.

Each DAC has a high-impedance differential-current

output, suitable for single-ended or differential analog

output configurations.

The DAC2900 combines high dynamic performance with

a high throughput rate to create a cost-effective solution

for a wide variety of waveform-synthesis applications:

• Pin compatibility between family members provides

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

(DAC2904) resolution.

• Pin compatible to the AD9763 dual DAC.

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

matching is specified at 0.02% max.

• The DAC2900 utilizes an advanced CMOS process; the

segmented architecture minimizes output glitch energy,

and maximizes dynamic performance.

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

The DAC2900 has an internal reference circuit, and

allows use of an external reference.

• The DAC2900 is available in a TQFP-48 package, and

is specified over the extended industrial temperature

range of –40°C to +85°C.
