Ground
External Positive Reference Input. Apply a reference
voltage at REF+. Bypass to GND with a 0.47FF
capacitor.
Power-Supply Input. Bypass to GND with a 10FF in
parallel with a 0.1FF capacitors.
Serial Clock Input. Clocks data in and out of the serial
interface
Active-Low Chip Select Input. When CS is low, the serial
interface is enabled. When CS is high, DOUT is high
impedance or three-state.
Serial Data Input. DIN data is latched into the serial
interface on the rising edge of SCLK.
Digital I/O Ground
Interface Digital Power-Supply Input. Bypass to GND
with a 10FF in parallel with a 0.1FF capacitors.
Serial Data Output. Data is clocked out on the falling
edge of SCLK. When CS is high, DOUT is high
impedance or three-state.
End of Conversion Output. Data is valid after EOC pulls
low (Internal clock mode only).
Exposed Pad. Connect EP directly to GND plane for
guaranteed performance.
