Frequently Asked Questions
How does the MCP4162-104E/P store its wiper position when power is removed?
The MCP4162-104E/P includes non-volatile EEPROM memory that retains the last programmed wiper position through power cycles, so the 100 kΩ resistance setting is restored at startup without requiring the host microcontroller to reinitialize the device.
What SPI clock speed does MCP4162-104E/P support for real-time resistance adjustment in control loops?
The MCP4162-104E/P supports SPI clock rates up to 10 MHz, allowing a host processor to update the wiper position across all 257 steps quickly enough for real-time gain or bias adjustment in closed-loop control and signal conditioning circuits.
For a benchtop calibration jig, how easy is it to replace a mechanical trimmer with MCP4162-104E/P?
The 8-pin PDIP package fits standard DIP sockets, and the 100 kΩ full-scale resistance with 257 positions provides fine resolution of about 390 Ω per step, closely matching the resolution of common 10-turn mechanical trimmers while adding remote digital control via SPI.
What is the supply voltage range for MCP4162-104E/P and does it support 3.3 V and 5 V systems?
The MCP4162-104E/P operates from 1.8 V to 5.5 V, making it compatible with both 3.3 V and 5 V logic systems without additional level shifters, and the SPI interface works at voltages down to 1.8 V for low-power microcontroller designs.
