Tri-State Digital-Data Output
Tri-State Digital-Data Output. D15 is the MSB.

R/
C
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 Input
Analog Ground. Connect pin 10 to pin 8.

REFADJ
Reference Buffer Output. Bypass REFADJ with a 0.1μF capacitor to AGND for internal reference
mode. Connect REFADJ to AV
DD
to select external reference mode.

REF
Reference Input/Output. Bypass REF with a 10μF capacitor to AGND for internal reference mode.
External reference input when in external reference mode.
