DESCRIPTION
The DAC902 is a high-speed, digital-to-analog converter (DAC)
offering a 12-bit resolution option within the SpeedPlus Family
of high-performance converters. Featuring pin compatibility
among family members, the DAC908, DAC900, and DAC904
provide a component selection option to an 8-, 10-, and 14-bit
resolution, respectively. All models within this family of D/A
converters support update rates in excess of 165MSPS with
excellent dynamic performance, and are especially suited to
fulfill the demands of a variety of applications.
The advanced segmentation architecture of the DAC902 is
optimized to provide a high Spurious-Free Dynamic Range
(SFDR) for single-tone, as well as for multi-tone signals—
essential when used for the transmit signal path of communica-
tion systems.
The DAC902 has a high impedance (200k) current output with
a nominal range of 20mA and an output compliance of up to
1.25V. The differential outputs allow for both a differential, or
single-ended analog signal interface. The close matching of the
current outputs ensures superior dynamic performance in the
differential configuration, which can be implemented with a
transformer.
Utilizing a small geometry CMOS process, the monolithic
DAC902 can be operated on a wide, single-supply range of
+2.7V to +5.5V. Its low power consumption allows for use in
portable and battery operated systems. Further optimization can
be realized by lowering the output current with the adjustable
full-scale option.
For noncontinuous operation of the DAC902, a power-down
mode results in only 45mW of standby power.
The DAC902 comes with an integrated 1.24V bandgap refer-
ence and edge-triggered input latches, offering a complete
converter solution. Both +3V and +5V CMOS logic families
can be interfaced to the DAC902.
The reference structure of the DAC902 allows for additional
flexibility by utilizing the on-chip reference, or applying an
external reference. The full-scale output current can be adjusted
over a span of 2mA to 20mA, with one external resistor, while
maintaining the specified dynamic performance.
The DAC902 is available in the SO-28 and TSSOP-28 pack-
ages.
