FUNCTION
Analog Single-Ended Input
Ground. This pin must connect to a solid ground plane.
Reference Input Pin
Positive Supply Voltage
Chip Select (Active Low). Initiates acquisition on the falling edge.
Digital I/O Supply Voltage (CS, DOUT, SCLK).
Serial Data Output. DOUT changes state on SCLK’s falling edge. See Figures 1 to 4 for details.
Serial Clock Input. SCLK drives the conversion process and clocks data out. See Figures 1 to 4 for
details.
