Pin Configuration

TABLE 3-1:	PIN FUNCTION TABLE
MCP4725
SOT-23	Name	Description
1	VOUT	Analog Output Voltage
2	VSS	Ground Reference
3	VDD	Supply Voltage
4	SDA	I²C Serial Data
5	SCL	I²C Serial Clock Input
6	A0	I²C Address Bit Selection pin (A0 bit). This pin can be tied to VSS or VDD, or can be actively driven by the digital logic levels. The logic state of this pin determines what the A0 bit of the I²C address bits should be.

Electrical Characteristics

† Notice: Stresses above those listed under "Maximum ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability

RL = 5 kΩ from VOUT to VSS, CL = 100 pF, TA = -40°C to +125°C. Typical values are at +25°C.
