General Description

AD9754 ICOMP RSET +5V IOUTA IOUTB LATCHES The AD9754 is a current-output DAC with a nominal full-scale output current of 20 mA and > 100 kΩ output impedance.

Differential current outputs are provided to support singleended or differential applications.

Matching between the two current outputs ensures enhanced dynamic performance in a differential output configuration.
