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.
