Read/Convert Input. Power up and place the MAX1179/MAX1187/MAX1189 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).
