Frequently Asked Questions
How many discrete resistance steps does the MCP4262-103E/UN provide per channel?
The MCP4262-103E/UN offers 257 wiper positions per channel, spanning a full-scale end-to-end resistance of 10 kΩ. Each step represents approximately 39 Ω of resolution, enabling fine-grained programmable resistance adjustment over a standard SPI bus operating up to 10 MHz.
Does the MCP4262-103E/UN retain wiper position after power is removed?
Yes, the MCP4262-103E/UN includes non-volatile EEPROM storage that saves wiper position through power cycles. This eliminates initialization code in systems that need fixed resistance values at startup, and allows each of the 2 channels to independently store its last-programmed 8-bit position value without host intervention.
Which circuit design scenarios call for a dual-channel digital potentiometer like MCP4262-103E/UN over a discrete trimmer?
Applications requiring remote calibration, production trimming over SPI, or dynamic gain adjustment in a -40°C to 125°C environment benefit from the MCP4262-103E/UN. Unlike mechanical trimmers, it tolerates vibration, supports automated test equipment workflows, and eliminates the 10 kΩ tolerance drift common in resistive trimmers after repeated mechanical cycling.
What PCB footprint does the MCP4262-103E/UN use and how does it compare to DIP alternatives?
MCP4262-103E/UN ships in a 10-pin MSOP package with a 3 mm × 3 mm footprint, roughly 70% smaller than a comparable 8-pin DIP potentiometer. This enables tighter board layouts in portable instruments and handheld devices while still supporting 1 kHz bandwidth across both independent resistance channels.
