Reference Voltage for analog-to-digital conversion. Also, Output of the Reference Buffer Amplifier
(4.096V in the MAX186, 1.638 x REFADJ in the MAX188). Add a 4.7μF capacitor to ground when
using external compensation mode. Also functions as an input when used with a precision external
reference.

VREF
Three-Level Shutdown Input. Pulling

low shuts the MAX186/MAX188 down to 10μA (max)
supply current, otherwise the MAX186/MAX188 are fully operational. Pulling
SHDN
high puts the ref-
erence-buffer amplifier in internal compensation mode. Letting
SHDN
float puts the reference-buffer
amplifier in external compensation mode.
