Pin Description
PIN NAME FUNCTION
1 D4/D12 Tri-State Digital-Data Output
2 D5/D13 Tri-State Digital-Data Output
3 D6/D14 Tri-State Digital-Data Output
4 D7/D15 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.
7AV
DD
Analog Supply Input. Bypass with a 0.1µF capacitor to AGND.
8 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 0.1µF capacitor to AGND for internal reference
mode. Connect REFADJ to AV
DD
to select external reference mode.
12 REF
Reference Input/Output. Bypass REF with a 10µF capacitor to AGND for internal reference mode.
External reference input when in external reference mode.
