AVDD
Analog Supply Input. AVDD is the power input for the analog section
of the converter. Apply 4.75V to 5.25V to AVDD. Bypass AVDD to
AGND (pin 14 to pin 15, pin 16 to pin 17, pin 1 to pin 2) with a 0.1F
capacitor at each AVDD input.

AGND
Analog Ground. AGND is the power return for AVDD. Connect all
AGNDs together.

MSV
Midscale Voltage Bypass. For the MAX1316/MAX1317/MAX1318,
connect a 2.2F and a 0.1F capacitor from MSV to AGND. For the
MAX1320/MAX1321/MAX1322/MAX1324/MAX1325/MAX1326,
connect MSV directly to AGND.
