Frequently Asked Questions
How many resistance steps does each channel of MCP4231-103E/P provide across its 10 kΩ range?
Each channel of MCP4231-103E/P provides 128 wiper positions across a 10 kΩ end-to-end resistance, giving a step resolution of approximately 78 Ω per increment. This is suitable for fine-grain gain adjustment, audio attenuation, and sensor calibration trims requiring precise analog control.
Does MCP4231-103E/P suit stereo audio designs, and what bandwidth does it support?
Yes. MCP4231-103E/P has two independent potentiometer channels in one 14-pin package, which is ideal for stereo left/right volume or balance control. The -3 dB bandwidth is 1 kHz, covering the full audible spectrum for consumer audio, hearing instruments, and laboratory signal generators.
Will the wiper position survive a power interruption in a field instrument?
MCP4231-103E/P stores wiper position in built-in non-volatile EEPROM, so both channels retain their 10 kΩ scale settings through power cycles without a backup battery or initialization firmware on every startup, which simplifies embedded code in handheld instruments.
For a new prototype build, how long does it take to source MCP4231-103E/P from Microchip distribution?
Factory lead time for MCP4231-103E/P is approximately 6 weeks from authorized Microchip distributors. Engineers ordering prototype quantities of 100 units or fewer can often find stock in distributor warehouses, while production-level orders of 1,000 units or more should be placed at least 8 weeks before the first board build.
