DESCRIPTION  
The DAC904 is a high-speed, Digital-to-Analog Converter (DAC)  
offering a 14-bit resolution option within the family of high-  
performance converters. Featuring pin compatibility among fam-  
ily members, the DAC908, DAC900, and DAC902 provide a  
component selection option to an 8-, 10-, and 12-bit resolution,  
respectively. All models within this family of DACs support  
update rates in excess of 165MSPS with excellent dynamic  
performance, and are especially suited to fulfill the demands of  
a variety of applications.  
For noncontinuous operation of the DAC904, a power-down  
mode results in only 45mW of standby power.  
The DAC904 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 DAC904.  
The reference structure of the DAC904 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 2-20mA, with one external resistor, while main-  
taining the specified dynamic performance.  
The advanced segmentation architecture of the DAC904 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 DAC904 is available in SO-28 and TSSOP-28 packages.  
The DAC904 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.
