Pin Configuration

The descriptions of the pins are listed in Table 3-1.

TABLE 3-1: PIN FUNCTION TABLE

MCP	4725	Name	Description
SOT-23	DFN	Name	Description
1	6	V _OUT	Analog Output Voltage
2	5	V _SS	Ground Reference
3	4	$V_{DD}$	Supply Voltage
4	3	SDA	I ² C Serial Data
5	2	SCL	I ² C Serial Clock Input
6	1	A0	$I^2C$ Address Bit Selection pin (A0 bit). This pin can be tied to $V_{SS}$ or $V_{DD}$ , or can be actively driven by the digital logic levels. The logic state of this pin determines what the A0 bit of the $I^2C$ address bits should be.
_	7	EP	Exposed Pad (Note 1)

Note 1: The DFN package has a contact on the bottom of the package. This contact is conductively connected to the die substrate, and therefore should be unconnected or connected to the same ground as the device's V_SS pin.
