Frequently Asked Questions - mcp4017 Microchip
What is the MCP4017?
The MCP4017 is a digital potentiometer from Microchip with 128 wiper steps over a 10 kΩ resistor array, controlled via an SPI interface.
What is the supply voltage range?
The operating supply voltage is from 1.8V to 5.5V, making it suitable for both 3.3V and 5V systems.
How is the wiper position set?
The wiper position is set by writing a 7-bit value to the internal register via the SPI interface. The value is stored in non-volatile memory using WiperLock technology.
Is the wiper setting retained after power-off?
Yes, the MCP4017 incorporates WiperLock technology that permanently sets the wiper position, which is retained even after power cycling.
What is the end-to-end resistance tolerance?
The standard resistance is 10 kΩ with ±20% tolerance. Other options like 50 kΩ and 100 kΩ are also available.
What package is available?
The MCP4017 is offered in the SC-70-5 package (also known as SOT-323-5).
Can the MCP4017 be used in audio applications?
Yes, with its low wiper resistance (typical 125 Ω) and 7-bit resolution, it is suitable for volume control and other audio adjustments.
What are the ESD precautions?
The device is ESD sensitive. Handle with proper ESD protection such as grounded wrist straps and conductive work surfaces.
Is the MCP4017 RoHS compliant?
Yes, the MCP4017 is RoHS compliant and lead-free.
Where can I find the datasheet?
The complete datasheet is available on the Microchip website under product MCP4017, or through authorized distributors.
