描述 Description

The Analog Devices AD9768SD D/A converter is a monolithic current-output converterwhich can accept 8 bits of ECL-level digital input voltages and convert them into analog signalsat update rates as high as 100MSPS.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 highas 40MHz.An inherently low glitch design is used, and the complementary current outputs are suitablefor driving transmission lines directly.Nominal full-scale output is 20mA, which corresponds to a 1-volt drop across a 50 Ohm load, or ±1 volt across 100 Ohm returned to +1volt.The actual output current is determined by the on-chip reference voltage (VREF-1.26V) and an external current setting resistor, RSET.
