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.
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.
Each DAC has a high-impedance differential-current out-
put, suitable for single-ended or differential analog-output
configurations.
APPLICATIONS
q COMMUNICATIONS:
Base Stations, WLL, WLAN
Baseband I/Q Modulation
q MEDICAL/TEST INSTRUMENTATION
q ARBITRARY WAVEFORM GENERATORS (ARB)
q DIRECT DIGITAL SYNTHESIS (DDS)
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 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.
• The DAC2900 is available in a TQFP-48 package, and is
specified over the extended industrial temperature range of
–40°C to +85°C.
