Read/Convert Input. Power up and put the MAX1178/MAX1188 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 Ground. Connect pin 10 to pin 8.
Reference Buffer Output. Bypass REFADJ with a 0.1µF capacitor to AGND for internal reference
mode. Connect REFADJ to AV
Reference Input/Output. Bypass REF with a 10µF capacitor to AGND for internal reference mode.
