Digital output enable input
High: high-impedance
Low: Normal operation
Digital ground
Analog ground
Internal reference voltage (high) generation. Shorting this pin to VrefH (pin 5) generates a voltage of 2.0 V.
This pin must be left open when the internally generated potential is not used.
Reference voltage input (high)
Analog input
Reference voltage intermediate level tap.
Reference voltage input (low)
Internal reference voltage (low) generation. Shorting this pin to VrefL (pin 8) generates a voltage of 0 V.
This pin must be left open when the internally generated potential is not used.
