DAC2900  
DAC2900  
SBAS166B – NOVEMBER 2003  
Dual, 10-Bit, 125MSPS  
DIGITAL-TO-ANALOG CONVERTER  
FEATURES  
● 125MSPS UPDATE RATE  
APPLICATIONS  
● COMMUNICATIONS:  
Base Stations, WLL, WLAN  
Baseband I/Q Modulation  
●
SINGLE SUPPLY: +3.3V or +5V  
● HIGH SFDR: 68dB at fOUT = 20MHz  
● LOW GLITCH: 2pVs  
● MEDICAL/TEST INSTRUMENTATION  
● ARBITRARY WAVEFORM GENERATORS (ARB)  
● DIRECT DIGITAL SYNTHESIS (DDS)  
● LOW POWER: 310mW at +5V  
● INTERNAL REFERENCE  
● POWER-DOWN MODE: 23mW  
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:  
DESCRIPTION  
The DAC2900 is a monolithic, 10-bit, dual-channel,  
high-speed Digital-to-Analog Converter (DAC), and is opti-  
mized to provide high dynamic performance while dissipat-  
ing only 310mW on a +5V single supply.  
• 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  
DAC2900 offers exceptional dynamic performance, and  
enables the generation of very-high output frequencies suit-  
able for “Direct IF” applications. The DAC2900 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 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 the 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.  
Each DAC has a high-impedance differential-current out-  
put, suitable for single-ended or differential analog-output  
configurations.  
• The DAC2900 is available in a TQFP-48 package, and is  
specified over the extended industrial temperature range of  
–40°C to +85°C.
