Applications
• DAC0830 linearly controls the current flow from the input terminal to the output terminal to be 4 mA (for D=0) to 19.94 mA (for
• Circuit operates with a terminal voltage differential of 16V to 55V.
•
• Digital inputs can be supplied from a processor using opto isolators on each input or the DAC latches can flow-through
• Output responds exponentially to input changes and automatically stops when V
D=255).
(connect control lines to pins 3 and 10 of the DAC) and the input data can be set by SPST toggle switches to ground (pins 3
and 10).
