General Description
nꢀ
10-bit resolution
CDK3400/3401 products are low-cost triple D/A converters that are tailored
to fit graphics and video applications where speed is critical. Two speed
grades are available: CDK3400 at 100MSPS and CDK3401 at 150MSPS.

TTL-level inputs are converted to analog current outputs that can drive
25-37.5Ω loads corresponding to doubly-terminated 50-75Ω loads. A sync
