Ground
Full-Scale Calibration Input. A resistor to ground on these pins determines the full-scale
current for each output. FS0 controls OUT0, FS1 controls OUT1, etc. (DS4402 has only
two inputs: FS0 and FS1.)
Current Output. Sinks or sources the current determined by the I
resistance connected to FSx. (DS4402 has only two outputs: OUT0 and OUT1.)
Address Select Inputs. Tri-level inputs (V
