Pin Description
FUNCTION
Analog Supply Input. AV_DD is the power input for the analog section
of the converter. Apply 4.75V to 5.25V to AV_DD. Bypass AV_DD to
AGND (pin 14 to pin 15, pin 16 to pin 17, pin 1 to pin 2) with a 0.1µF
capacitor at each AV_DD input.
Analog Ground. AGND is the power return for AV_DD. Connect all
AGNDs together.
Channel 0 Analog Input
Channel 1 Analog Input
Midscale Voltage Bypass. For the MAX1316/MAX1317/MAX1318,
connect a 2.2µF and a 0.1µF capacitor from MSV to AGND. For the
MAX1320/MAX1321/MAX1322/MAX1324/MAX1325/MAX1326,
connect MSV directly to AGND.
