Name Function
GND Analog ground
VDD
Analog +5 V
OGND Output ground
OVDD Supply voltage for digital outputs 3 V/5 V
REFL
Reference pin low, input for external
reference, bypass with capacitor (10 µF)
when internal reference is selected.
REFH
Reference pin high, input for external
reference, bypass with capacitor (10 µF)
when internal voltage is selected.
VCM
2.5 V common mode voltage reference output
VIN
Non-inverted analog input
VIN
Inverted analog input
CLK
Clock input pin
CLK
Complement of clock input pin, internally
biased to 1.5 V; if single-ended clock is used,
bypass to GND with 10 µF
D0–D9 Digital outputs; D0 = LSB; 3 V/5 V compatible
OR
Out-of-range bit; 3 V/5 V compatible
EXT/INT EXT/INT = 1, external reference used; internal
reference powered down
EXT/INT = 0, internal reference used;
internally pulled down
Sleep
Sleep = 1, normal operation; internally pulled
up
Sleep = 0, powered-down mode
