Tri-State Digital-Data Output. D15 is the MSB.
5R/
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.
6
EOC
End of Conversion.
EOC drives low when conversion is complete.
7AVDD
Analog Supply Input. Bypass with a 0.1F capacitor to AGND.

AGND
Analog Ground. Primary analog ground (star ground).
9
AIN
Analog Input
10
AGND
Analog Ground. Connect pin 10 to pin 8.
11
REFADJ
Reference Buffer Output. Bypass REFADJ with a 0.1F capacitor to AGND for internal reference
mode. Connect REFADJ to AVDD to select external reference mode.
12
REF
Reference Input/Output. Bypass REF with a 10F capacitor to AGND for internal reference mode.
External reference input when in external reference mode.
