10

URB

Underange Output. URB is asserted low when the analog input voltage is below the RB pin voltage.

11

WOUTB

Window Output. WOUTB is asserted low when the analog input voltage is between the RB pin voltage and the

RT pin voltage.

12

ORB

Overrange output. ORB is asserted low when the analog input voltage range is above the RT pin voltage.

15

RTN

ESD Protection Return.
