MCP42XXEV

The MCP42XXEV is an evaluation board allows the system designer to quickly evaluate the operation of the MCP4261 digital potentiometer device using the PICkit Serial analyser. This board is a minimum configuration for the device. As well as the device, other desired passive components (resistors and capacitors) and connection posts may be installed. The board can also be very easily jumpered into a customer's existing circuit. This gives an indication of the MCP4261 device performance, but is affected by the jumper lead length and the EM noise that the jumpers pick up. The device's resistor network 0 has been configured in a potentiometer mode with the a terminal connected to VDD through a 0R resistor and the B terminal connected to VSS with a 0R resistor. Resistor network 1 can be evaluated for rheostat operation. The MCP42XXEV evaluation board uses the generic TSSOP20EV evaluation board PCB.
