DESCRIPTION

The DAC904 is a high-speed, Digital-to-Analog Converter (DAC)

offering a 14-bit resolution option within the family of highperformance

converters. Featuring pin compatibility among family

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.

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 communication

systems.

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.

Utilizing a small geometry CMOS process, the monolithic DAC904

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 DAC904, a power-down

mode results in only 45mW of standby power.

The DAC904 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 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 maintaining

the specified dynamic performance.

The DAC904 is available in SO-28 and TSSOP-28 packages.
