Pin Function Table (6 Pins)
Pin Number Pin Name Pin Type Function Description 1 VDD Power This pin is the positive supply voltage. It is connected to a regulated voltage source (typically 2.7V to 5.5V). 2 VSS Power This pin is the ground. It is connected to the system ground (0V). 3 SDA I/O Serial Data Input. This pin is used for data communication (I2C). It carries the data sent to the device. 4 SCL I/O Serial Clock Input. This pin is used for clock signal (I2C), dictating the timing of data transfer. 5 A0 Input DAC Address Pin. This pin allows you to select the I2C address of the MCP4725. It is typically connected to ground or VDD depending on the desired address. 6 VOUT Output Output Voltage. This is the analog output of the DAC, which reflects the converted voltage.General Circuit Principle
The MCP4725A0T-E/CH is a 12-bit, I2C-controlled DAC. The I2C interface (SDA and SCL) is used to send commands to the DAC, which then converts the 12-bit data to an analog voltage, output through the VOUT pin. The DAC output is dependent on the voltage applied to VDD and the digital value sent via I2C.
The VDD and VSS pins provide the necessary power for the device. The SDA and SCL pins interface with a microcontroller or other I2C master device. The A0 pin configures the I2C address, enabling you to control multiple MCP4725 devices on the same I2C bus. The VOUT pin provides the analog output corresponding to the DAC value.Frequently Asked Questions (FAQ) for MCP4725A0T-E/CH
