SPI – Serial Data Input Pin (SDI)

The SDI pin is the serial data input pin of the SPI

interface. The SDI pin is used to read the DAC registers

and Configuration bits.

See Section 6.2 “SPI Serial Interface” for more

details on the SPI serial interface communication.

3.8

SPI – Serial Data Output Pin (SDO)

The SDO pin is the serial data output pin of the SPI

interface. The SDO pin is used to write the DAC

registers and Configuration bits.

See Section 6.2 “SPI Serial Interface” for more

details on the SPI serial interface communication.

3.9

SPI – Serial Clock Pin (SCK)

The SCK pin is the serial clock pin of the SPI interface.

The MCP48FXBX4/8 SPI interface only accepts

external serial clocks.

See Section 6.2, SPI Serial Interface for more details

on the SPI serial interface communication.

3.10

No Connect Pin (NC)

The NC pins are not connected to the device.

3.11

Exposed Pad Pin

This pad is conductively connected to the device’s

substrate. It should be tied to the same potential as the

VSS pin (or left unconnected). This pad could be used

to assist in heat dissipation for the device when con-

nected to a PCB heat sink. The pad is only present on

the VQFN package.
