VDD
P
Power Supply. Nominally 2.5 V to 5.5 V when using an external reference and decoupled
with 10 μF and 100 nF capacitors.
When using the internal reference for a2.5 V output, the minimum should be 3.0 V.
When using the internal reference for 4.096 V output, the minimum should be 4.6 V.
2
REF
AI/O
Reference Input/Output. See the Voltage Reference Output/Input section.
When the internal reference is enabled, this pin produces a selectable system reference of
2.5 V or 4.096 V.
When the internal reference is disabled and the buffer is enabled, REF produces a
buffered version of the voltage present on the REFIN pin (VDD 0.5 V maximum), which
is useful when using low cost, low power references.
For improved drift performance, connect a precision reference to REF (0.5 V to VDD).
For any reference method, this pin needs decoupling with an external 10 μF capacitor
connected as close to REF as possible. See the Reference Decoupling section.
3
REFIN
AI/O
Internal Reference Output/Reference Buffer Input. See the Voltage Reference
Output/Input section.
When using the internal reference, the internal unbuffered reference voltage is present
and needs decoupling with a 0.1 μF capacitor.
When using the internal reference buffer, apply a source between 0.5 V and (VDD 0.5 V)
that is buffered to the REF pin, as described in the REF pin description.

Common Channel Input. All input channels, IN[7:0], can be referenced to a common-

CNV
DI
Conversion Input. On the rising edge, CNV initiates the conversion. During conversion, if
CNV is held low, the busy indictor is enabled.
12
DIN
DI
Data Input. This input is used for writing to the 14-bit configuration register. The
configuration register can be written to during and after conversion.
13
SCK
DI
Serial Data Clock Input. This input is used to clock out the data on SDO and clock in data
on DIN in an MSB first fashion.
