wide variety of waveform-synthesis applications:

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.

• 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

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.

• 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.

Each DAC has a high-impedance differential-current output,

suitable for single-ended or differential analog-output con-

figurations.

• The DAC2902 is available in a TQFP-48 package, and is

specified over the extended industrial temperature range of

–40°C to +85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
