Sampling Analog Inputs
9
VSS
Negative Supply Voltage. Connect to -5V ±5% or AGND
10
SHDN
Three-Level Shutdown Input. Pulling
SHDN low shuts the MAX186/MAX188 down to 10μA (max)
supply current, otherwise the MAX186/MAX188 are fully operational. Pulling
SHDN high puts the
reference-buffer amplifier in internal compensation mode. Leaving
SHDN unconnected puts the
reference-buffer amplifier in external compensation mode.
11
VREF
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
