DESCRIPTION  
The DAC900 is a high-speed, digital-to-analog converter (DAC)  
offering a 10-bit resolution option within the SpeedPlus family  
of high-performance converters. Featuring pin compatibility  
among family members, the DAC908, DAC902, and DAC904  
provide a component selection option to an 8-, 12-, 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 DAC900 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 DAC900.  
The reference structure of the DAC900 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 advanced segmentation architecture of the DAC900 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 DAC900 is available in SO-28 and TSSOP-28 packages.

The DAC900 has a high impedance (200kΩ) 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  
DAC900 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.
