FUNCTIONAL BLOCK DIAGRAM
The Analog Devices AD9768SD D/A converter is a monolithic current-output converter which can accept 8 bits of ECL-level digital input voltages and convert them into analog signals at update rates as high as 100 MSPS. In addition to its use as a standard D/A converter, it can also be utilized as a two-quadrant multiplying D/A at multiplying bandwidths as high as 40 MHz. An inherently low glitch design is used, and the plementary current outputs are suitable for driving transmission lines directly. Nominal full-scale output is 20 m A, which corresponds to a 1 volt drop across a 50 Ω load, or ± 1 volt across 100 Ω returned to +1 volt. The actual output current is determined by...
