SPT5240
10-BIT, 400 MHz CURRENT OUTPUT D/A CONVERTER
PRELIMINARY INFORMATION
DECEMBER 15, 2001
FEATURES
400 MWPS update rate
Differential current output
+3.3 V power supply
Ultralow power dissipation:
140 mW (typ) @CLK = 400 MHz
Power-down mode draws less than 5 nA from AVDD
and 200 A from DVDD with no clock or data
Excellent AC performance:
SFDR = –57 dBc for CLK = 400 MHz and
OUT = 1.27 MHz
Internal reference
APPLICATIONS
Battery-operated devices
Portable RF devices
Set top boxes
Video displays
Broadband RF
High-speed test equipment
GENERAL DESCRIPTION
The SPT5240 is a 10-bit digital-to-analog converter that
performs at an update rate of 400 M words per second.
The part is implemented in a 0.25 m CMOS process. The
architecture achieves excellent high-frequency perfor-
mance with very low power dissipation. This makes it ideal
for all types of battery-operated equipment requiring high-
speed digital-to-analog conversion.
The SPT5240 operates over an extended industrial tem-
perature range from –40 °C to +85 °C and is available in a
32-lead TQFP package.
