Frequently Asked Questions
What is the end-to-end resistance of the MCP4641-503E/ST, and how fine is each resistance step?
The MCP4641-503E/ST has a 50 kΩ end-to-end resistance divided into 128 steps, resulting in a step size of approximately 390 Ω per increment. This resolution allows accurate programmable resistance settings across a wide range for gain control, filtering, and calibration circuits.
Does the MCP4641-503E/ST lose its programmed resistance when the board loses power?
No, the MCP4641-503E/ST includes non-volatile EEPROM that retains the programmed wiper position indefinitely after power is removed. On the next power-up the device immediately resumes at the stored resistance value, removing any need for the host processor to reconfigure the potentiometer on every boot cycle.
How does the MCP4641-503E/ST compare to the MCP4242-502E/UN for designs needing higher resistance values?
The MCP4641-503E/ST offers a 50 kΩ end-to-end resistance versus the 5 kΩ of the MCP4242-502E/UN, making it ten times more suitable for high-impedance signal conditioning circuits such as feedback networks in precision op-amp stages or voltage dividers where loading the source signal must be minimized.
