Ground
Internally Connected. Connect to ground. (Reference Input, MAX1118 only.)
Convert/Start Input. CNVST initiates a power-up and starts a conversion on its falling edge.
Serial Data Output. Data is clocked out on the falling edge of SCLK. DOUT goes low at the start of a
conversion and presents the MSB at the completion of a conversion. DOUT goes high impedance
once data has been fully clocked out.
Serial Clock. Used for clocking out data on DOUT.
