MCP3421EV Datasheet PDF - Microchip

●The MCP3421EV is an evaluation board for MCP3421 SOT23-6 18bit delta sigma analog to digital converter (ADC). The MCP3421 is an 18bit single channel ADC device with various options. The MCP3421 SOT23-6 evaluation board has analog input connection pads and VDD, SDA, and SCL test pads. The user can connect any sensor input signal to this evaluation board and test the ADC conversion results. The PICkit Serial analyser"s PC graphic user interface provides the user"s interface for writing configuration register bits of the MCP3421 and displays the ADC conversion values. The PICkit Serial analyser links between the GUI and the MCP3421 SOT23-6 evaluation Board, and provides the I2C communication PC to the MCP3421 SOT23-6 evaluation Board. The user can also use this MCP3421 SOT23-6 evaluation Board without the PICkit Serial analyser by providing the I2C communication signal to the SDA and SCL test pads on the board.

● The MCP3421EV works with the PICkit serial analyser

● Board allows the user to measure the unknown input voltage with a minimum amount of preparation

● Write and read the MCP3421 configuration register bits using the PICkit serial analyser

● Read the ADC conversion results using the PICkit serial analyser

● Many test pads including the SCL and SDA allow to monitor the I2C signals data communications

● User can connect the SDA and SCL pins to their own PCB board and evaluate the MCP3421 performance

●The user can use this board without the PICkit Serial analyser as long as the VDD, SCL, and SDA are provided to the board. This evaluation board does not include MCU.
