Pin Description
FUNCTION
Lower Reference. Conversion range is ±(VREFP - VREFN). Bypass to GND with a >0.1µF
capacitor.
Common-Mode Voltage Output. Bypass to GND with a >0.1µF capacitor.
Analog Supply Voltage. Bypass to GND with a capacitor combination of 2.2µF in parallel
with 0.1µF.
Analog Ground
Positive Analog Input. For single-ended operation, connect signal source to IN+.
Negative Analog Input. For single-ended operation, connect IN- to COM.
Conversion Clock Input
Power-Down Input
High: power-down mode
Low: normal operation
Output Enable Input
High: digital outputs disabled
Low: digital outputs enabled
Three-State Digital Outputs D9–D5. D9 is the MSB.
Output Driver Supply Voltage. Bypass to GND with a capacitor combination of 2.2µF in
parallel with 0.1µF.
Test Point. Do not connect.
Output Driver Ground
Three-State Digital Outputs D4–D0. D0 is the LSB.
Internal Reference Voltage Output. May be connected to REFIN through a resistor or a
resistor-divider.
Reference Input. VREFIN = 2 × (VREFP - VREFN). Bypass to GND with a >0.01µF capacitor.
Upper Reference. Conversion range is ±(VREFP - VREFN). Bypass to GND with a >0.1µF
capacitor.
