Pin Description
PIN
NAME
FUNCTION
1
REFN
Lower Reference. Conversion range is
±(VREFP - VREFN).
Bypass to GND with a > 0.1
μF capacitor.
2
COM
Common-Mode Voltage Output. Bypass to GND with a >0.1
μF capacitor.
3, 9, 10
VDD
Analog Supply Voltage. Bypass to GND with a capacitor combination of 2.2
μF in parallel
with 0.1
μF.
4, 5, 8, 11, 14, 30
GND
Analog Ground
6
IN+
Positive Analog Input. For single-ended operation, connect signal source to IN+.
7
IN-
Negative Analog Input. For single-ended operation, connect IN- to COM.
12
CLK
Conversion Clock Input
13
PD
Power Down Input. High: Power-down mode. Low: Normal operation.
15
OE
Output Enable Input. High: Digital outputs disabled. Low: Digital outputs enabled.
16–20
D9–D5
Three-State Digital Outputs D9–D5. D9 is the MSB.
21
OVDD
Output Driver Supply Voltage. Bypass to GND with a capacitor combination of 2.2
μF in
parallel with 0.1
μF.
22
T.P.
Test Point. Do not connect.
23
OGND
Output Driver Ground
24–28
D4–D0
Three-State Digital Outputs D4–D0. D0 is the LSB.
29
REFOUT
Internal Reference Voltage Output. May be connected to REFIN through a resistor or a
resistor-divider.
31
REFIN
Reference Input. VREFIN = 2
× (VREFP - VREFN). Bypass to GND with a >0.1μF capacitor.
32
REFP
Upper Reference. Conversion range is
±(VREFP - VREFN). Bypass to GND with a >0.1μF
capacitor.
