Description
The SPT5240 is a 10-bit digital-to-analog converter that
performs at an update rate of 400M words per second. The
architecture achieves excellent high-frequency performance
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
temperature range from -40°C to +85°C and is available in a
32-lead LQFP package.
