DESCRIPTION
The DAC2902 is a monolithic, 12-bit, dual-channel,
high-speed Digital-to-Analog Converter (DAC), and is opti-
mized to provide high dynamic performance while dissipating
only 310mW.
Operating with high update rates of up to 125MSPS, the
DAC2902 offers exceptional dynamic performance, and
enables the generation of very-high output frequencies suit-
able for “Direct IF” applications. The DAC2902 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 output,
suitable for single-ended or differential analog-output con-
figurations.
The DAC2902 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 AD9765 dual DAC.
Gain matching is typically 0.5% of full-scale, and offset
matching is specified at 0.02% max.
The DAC2902 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
DAC2902 has an internal reference circuit, and allows use
of an external reference.
The DAC2902 is available in a TQFP-48 package, and is
specified over the extended industrial temperature range of
–40°C to +85°C.
