Frequently Asked Questions
How many resistance steps does the MCP4242-502E/UN provide, and what is its end-to-end resistance?
The MCP4242-502E/UN offers 128 wiper positions (7-bit resolution) across a 5 kΩ end-to-end resistance, giving a step size of approximately 39 Ω per step. This fine step resolution enables accurate programmable resistance settings for gain control and calibration circuits.
Does the MCP4242-502E/UN retain its wiper position when power is removed?
Yes, the MCP4242-502E/UN includes non-volatile EEPROM memory that stores the last wiper position across power cycles. This eliminates the need for the host microcontroller to reinitialize the potentiometer on every power-up, which is important in battery-powered or field-deployed equipment.
For a compact portable design, how small is the MCP4242-502E/UN package footprint?
The MCP4242-502E/UN is housed in a 10-pin MSOP package with a body size of approximately 3 mm × 3 mm, making it one of the smallest dual digital potentiometer options available. It fits easily on dense PCBs where a larger SOIC-16 dual potentiometer would not be practical.
