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.
