Key Features
- Single-channel 5 kOhm digital potentiometer with 128 wiper positions providing fine-grained resistance adjustment
- SPI-compatible increment/decrement interface enabling simple 2-wire MCU control without address decoding overhead
- Compact SOIC-8 package with 2.7 V to 5.5 V supply range for mixed-voltage analog trimming circuits
Applications
The MCP4132-502E/SN is used for digitally controlled gain adjustment in audio preamps, sensor signal-conditioning circuits, and LCD contrast control where a 5 kOhm variable element with 128-step resolution replaces a mechanical potentiometer. Its SPI interface allows real-time wiper adjustment from any microcontroller running at 3.3 V or 5 V without extra level-translation hardware. Calibration trim circuits in industrial meters and LED dimming controllers also benefit from its single-supply operation down to 2.7 V.

Frequently Asked Questions
How many resistance steps does the MCP4132 provide, and what step size does that yield at 5 kOhm full-scale?
The MCP4132 offers 128 wiper positions across a 5 kOhm end-to-end resistance, giving a nominal step size of approximately 39 Ohm per increment. This fine resolution allows precise gain-trim loops in op-amp circuits requiring less than 1% adjustment accuracy.
What SPI clock speed does the MCP4132 support, and how does increment/decrement control work in practice?
The MCP4132 accepts SPI clock rates up to 10 MHz for register writes. Its increment/decrement command interface sends a single byte per wiper step, allowing a microcontroller to traverse all 128 positions in under 13 µs — fast enough for real-time audio volume sweeps.
For a battery-powered calibration tool, what supply voltage range does the MCP4132 support?
The MCP4132 operates from 2.7 V to 5.5 V, making it compatible with both 3 V coin-cell-powered instruments and 5 V industrial control boards without external regulators. Its typical quiescent current is below 1 µA in standby, extending battery life in portable trim fixtures.
How does the MCP4132 differ from the MCP4131 and when should each be chosen?
The MCP4132 is a single-channel potentiometer with volatile wiper storage (wiper resets to mid-scale at power-up), whereas the MCP4131 shares the same 5 kOhm / 128-step architecture but uses an SPI chip-select scheme compatible with daisy-chaining multiple devices. Choose MCP4132 for simple single-device trims; choose MCP4131 when 2 or more potentiometers share a single SPI bus without extra chip-select lines.
