MSV
Midscale Voltage Bypass.
For the unipolar MAX1304/MAX1305/MAX1306,
connect a 2.2μF and a 0.1μF capacitor from MSV to AGND. For the bipolar
MAX1308/MAX1309/MAX1310/MAX1312/MAX1313/MAX1314, connect
MSV to AGND.

REF
MS
Midscale Reference Bypass or Input.
REF
MS
connects through a 5k
resistor to
the internal +2.5V bandgap reference buffer.
For the MAX1304/MAX1305/MAX1306 unipolar devices, V
REFMS
is the input to
the unity-gain buffer that drives MSV.
MSV sets the midpoint of the input voltage
range.
For internal reference operation, bypass REF
MS
with a
≥
0.01μF
capacitor to AGND.
For external reference operation, drive REF
MS
with an
external voltage from +2V to +3V.
For the MAX1308/MAX1309/MAX1310/MAX1312/MAX1313/MAX1314 bipolar
devices, connect REF
MS
to REF.
For internal reference operation, bypass the
REF
MS
/REF node with a
≥
0.01μF capacitor to AGND.
For external reference
operation, drive the REF
MS
/REF node with an external voltage from +2V to +3V.
ADC Reference Bypass or Input. REF connects through a 5k
resistor to the
internal +2.5V bandgap reference buffer.
For internal reference operation, bypass REF with a
≥
0.01μF capacitor.
For external reference operation with the MAX1304/MAX1305/MAX1306
unipolar devices, drive REF with an external voltage from +2V to +3V.
For external reference operation with the MAX1308/MAX1309/MAX1310/
MAX1312/MAX1313/MAX1314 bipolar devices, connect REF
MS
to REF and
drive the REF
MS
/REF node with an external voltage from +2V to +3V.
