What are the key features of MCP4662-104E/UN?
- Non-volatile memory retains the 256-step wiper position through power cycles, eliminating recalibration on startup
- 100 kΩ end-to-end resistance with 256 steps provides approximately 391 Ω per step for fine-grained adjustment
- Dual independent potentiometer channels in one 10-pin MSOP package reduce component count in 2-axis or dual-parameter trim circuits
- Increment/decrement control interface allows simple push-button or GPIO control without a full SPI/I2C bus
- RoHS-compliant lead-free MSOP-10 package with 0.5 mm pitch supports high-density SMT assembly
What is MCP4662-104E/UN used for?
The MCP4662-104E/UN is suited for programmable gain amplifiers, electronic volume controls, and sensor offset trim circuits in industrial calibration equipment and consumer electronics where the wiper position must be retained after power removal. Its dual-channel architecture with non-volatile storage makes it valuable in automatic test equipment front ends and audio mixing consoles that require independent channel gain adjustments that persist across power cycles. The device is also used in LCD display brightness and contrast control, motor speed trim, and DAC reference voltage adjustment circuits operating from 2.7 V to 5.5 V supplies.

Frequently Asked Questions
How does the non-volatile memory in the MCP4662-104E/UN benefit field-calibration applications?
The MCP4662-104E/UN stores its 256-step wiper position in non-volatile memory, so the calibrated resistance setting of 0 Ω to 100 kΩ is retained after power is removed. This eliminates the need for a microcontroller to reload calibration data on startup, reducing firmware complexity and improving system reliability in field-deployed sensors and instruments that may be power-cycled repeatedly.
What resistance resolution does the MCP4662-104E/UN provide and is it fine enough for gain trimming in a precision amplifier?
With 256 steps over a 100 kΩ range, the MCP4662-104E/UN provides a step size of approximately 391 Ω per increment. In a gain-setting resistor divider for a precision op-amp with a nominal gain of 10 V/V, this corresponds to a gain adjustment resolution of roughly 0.04 V/V per step, sufficient for trimming amplifier gain to within 0.5% accuracy in most instrumentation and weighing scale applications.
What are the two channels in the MCP4662-104E/UN used for independently and how are they controlled?
The MCP4662-104E/UN contains 2 independent 100 kΩ digital potentiometer channels, each controllable via increment and decrement inputs with separate chip-select lines, allowing independent adjustment of two gain stages, two audio channels, or two bias voltages without cross-coupling. Each channel's 256-step wiper position is stored independently in non-volatile memory, maintaining separate calibration values across power cycles.
In a 5 V audio volume control circuit, how many discrete volume steps does the MCP4662-104E/UN provide and over what range?
The MCP4662-104E/UN provides 256 discrete wiper positions over its 100 kΩ end-to-end resistance in a volume control application, corresponding to approximately 256 volume steps from minimum to maximum attenuation. In a voltage-divider configuration with a 5 V audio signal, each step adjusts the output by approximately 19.6 mV, allowing smooth volume adjustment from 0 V (mute) to near 5 V with sub-20 mV resolution suitable for consumer audio equipment.
