The MCP402X devices are non-volatile, 6-bit (64 wiper steps) digital potentiometers with a simple up/down serial interface. The MCP402X devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count. The MCP4021 device offers a voltage divider (potentiometer), with all terminals available on pins. The MCP4022 is a true rheostat, with both nodes of the resistor available on pins. The MCP4023 device offers a voltage divider (potentiometer), with one terminal connected to ground. The MCP4024 device is a rheostat mode device, with one terminal of the resistor connected to ground. The devices offer WiperLock™ Technology which allows the user unlimited reprogramming and locking of the wiper setting. This is useful for equipment that requires factory trimming or recalibration. The MCP402X family of devices are available with resistor values of 2.5kΩ, 5kΩ, 10kΩ and 50kΩ. These devices operate from a single 2.7-5.5V supply and draw less than 1 µA while operating in the static state. Also consider using the MCP4021, MCP4023 and MCP4024
The MCP402xEV is a low cost evaluation board that quickly enables the user to exercise all of the features of the MCP402X Non-Volatile Digital Potentiometer. This kit includes 2 PCBs, one populated & one unpopulated. The populated PCB has an MCP4021-103E/SN digital pot configured as a “windowed” potentiometer using a 2.5kΩ pull-up and a 2.5kΩ pull-down resistor. The PCB supports...
This Blank PCB allows the system designer to quickly evaluate the operation of Microchip Technology’s Voltage Supervisors and Voltage Detectors in the SOT-23-5 (5-pin) and SOT-23-6 (6-pin) packages. This PCB supports many Microchip device families, including the Nonvolitile Digital Potentiometer and PIC10F2xx devices.
