Read/Convert Input. Power up and put the MAX1065/MAX1066 in acquisition
mode by holding R/C low during the first falling edge of CS. During the
second falling edge of CS the level on R/C determines whether the reference
and reference buffer power down or remain on after conversion. Set R/C high
during the second falling edge of CS to power down the reference and buffer,
or set R/C low to leave the reference and buffer powered up. Set R/C high
during the third falling edge of CS to put valid data on the bus.
End Of Conversion. EOC drives low when conversion is complete.
Analog Supply Input. Bypass with a 0.1µF capacitor to AGND.
Analog Ground. Primary analog ground (star ground).
Analog Input
Analog Ground. Connect Pin 14 to Pin 12 (MAX1065). Connect Pin 10 to Pin 8
(MAX1066).
