DAC900

SBAS093B – MAY 2002

10-Bit, 165MSPS

DIGITAL-TO-ANALOG CONVERTER

FEATURES

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 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.

● SINGLE +5V OR +3V OPERATION

●

HIGH SFDR: 5MHz Output at 100MSPS: 68dBc

● LOW GLITCH: 3pV-s

● LOW POWER: 170mW at +5V

● INTERNAL REFERENCE:

Optional Ext. Reference

Adjustable Full-Scale Range

Multiplying Option

The advanced segmentation architecture of the DAC900 is opti-

mized 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 communication systems.

APPLICATIONS

● COMMUNICATION TRANSMIT CHANNELS

WLL, Cellular Base Station

Digital Microwave Links

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.

Cable Modems

● WAVEFORM GENERATION

Direct Digital Synthesis (DDS)

Arbitrary Waveform Generation (ARB)

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.

● MEDICAL/ULTRASOUND

● HIGH-SPEED INSTRUMENTATION AND CON-

TROL

For noncontinuous operation of the DAC900, a power-down mode

results in only 45mW of standby power.

● VIDEO, DIGITAL TV

The DAC900 comes with an integrated 1.24V bandgap reference

and edge-triggered input latches, offering a complete converter

solution. Both +3V and +5V CMOS logic families can be inter-

faced to the DAC900.

The reference structure of the DAC900 allows for additional

flexibility by utilizing the on-chip reference, or applying an exter-

nal reference. The full-scale output current can be adjusted over a

span of 2mA to 20mA, with one external resistor, while maintain-

ing the specified dynamic performance.
