NAME FUNCTION
1, 15, 17 1, 15, 17 1, 15, 17 AV
DD
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.
2, 3, 14, 16, 23 2, 3, 14, 16, 23 2, 3, 14, 16, 23 AGND
Analog Ground. AGND is the power return for AV
DD
. Connect all
AGNDs together.
4 4 4 CH0 Channel 0 Analog Input
5 5 5 CH1 Channel 1 Analog Input
666MSV
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.
