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 device 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.
13 HBEN
High-Byte Enable Input. Used to multiplex the 16-bit conversion result.
1: MSB available on the data bus.
0: LSB available on the data bus.
14 CS
Convert Start. The first falling edge of CS powers up the device and enables acquire mode when R/C
is low. The second falling edge of CS starts the conversion. The third falling edge of CS loads the
result onto the bus when R/C is high.
15 DGND Digital Ground
16 DV
DD
Digital Supply Voltage. Bypass with a 0.1µF capacitor to DGND.
17 D0/D8 Tri-State Digital-Data Output. D0 is the LSB.
18 D1/D9 Tri-State Digital-Data Output
19 D2/D10 Tri-State Digital-Data Output
20 D3/D11 Tri-State Digital-Data Output
