Pin Functions
V
ref (Pin 6):
Reference Output. Capable of sourcing up to 8mA.
Input (Pin 2):
Positive Supply.
Ground (Pins 1, 4, 7, 8):
Negative Supply or Ground Connection. These pins must be
connected to ground.
Enable (Pin 3):
Pulled to input for normal operation. Forcing this pin to ground will
turn-off the output.
