Key Features
- Dual independent 100 kΩ channels with 257-step linear resolution over I2C for fine-grained voltage and resistance tuning
- Non-volatile wiper position memory retains settings through power cycles without host firmware intervention
- Wide 1.8 V to 5.5 V supply range in a 10-pin MSOP package, compatible with both 3.3 V and 5 V microcontroller systems
Applications
The MCP4652-104E/UN suits applications requiring software-adjustable resistance or voltage, such as programmable gain amplifiers, LCD contrast and backlight controls, and sensor calibration circuits. Its I2C interface allows daisy-chaining multiple devices at different addresses, enabling multi-channel trimming with only 2 signal wires. Non-volatile wiper storage makes it ideal for factory calibration workflows where the adjusted value must persist after power-off without a host processor.

Frequently Asked Questions
How many discrete resistance steps does the MCP4652-104E/UN provide across its 100 kΩ range?
The MCP4652-104E/UN offers 257 wiper positions across a 100 kΩ end-to-end resistance, giving a step resolution of approximately 391 Ω per LSB. For the 5 kΩ variant each step is about 19.5 Ω, and for the 10 kΩ variant roughly 39 Ω per step. This fine granularity is sufficient for precise gain trimming in 12-bit instrumentation amplifier designs where gain error must stay below 0.1%.
Does the MCP4652-104E/UN retain its wiper position after power is removed, and what retention period is guaranteed?
Yes. The MCP4652-104E/UN stores the wiper position in non-volatile EEPROM with a minimum 100-year data retention and 100,000-cycle endurance. On power-up the wiper automatically returns to the saved position without any I2C command, making it ideal for factory calibration workflows where the trimmed value must survive field power cycles and shipping conditions.
How many MCP4652-104E/UN devices can share one I2C bus, and how are addresses configured?
The MCP4652 family uses hardware address pins to select from up to 8 unique I2C addresses on a single bus. With 8 dual-channel devices on one bus, a designer gains 16 independently adjustable 100 kΩ potentiometer channels using only the 2-wire SDA/SCL pair, minimizing wiring complexity in multi-axis calibration boards and audio mixer applications.
For a programmable gain stage requiring resistance values between 5 kΩ and 100 kΩ, is the MCP4652-104E/UN the right choice or should the 5 kΩ variant be used?
The -104 suffix denotes the 100 kΩ end-to-end resistance version, spanning 391 Ω to 100 kΩ in 257 steps. If the gain stage needs fine control below 5 kΩ, the MCP4652-502 (5 kΩ) provides 19.5 Ω per step resolution in the same 10-pin MSOP footprint and is pin-compatible. For ranges above 5 kΩ the 100 kΩ version covers the full span, keeping the gain error within the 2 kHz bandwidth specification.
