Key Features
- 256-step wiper resolution on a 50 kΩ resistor array provides fine-grained resistance control from approximately 195 Ω to 50 kΩ per channel
- I2C 2-wire serial interface minimizes GPIO usage on the host MCU, enabling control with just SCL and SDA lines shared with other bus devices
- Dual-channel configuration (2 independent potentiometers) in a single 10-pin MSOP package reduces BOM and PCB footprint versus two separate devices
- Non-volatile wiper position memory retains the last set resistance value through power cycles, eliminating initialization overhead in production equipment
Applications
MCP4652-503E/UN is used for programmable gain control, bias voltage trimming, and calibration in precision analog circuits where an MCU must adjust resistance digitally over I2C without mechanical access. Audio volume control, LCD contrast adjustment, and sensor signal conditioning circuits benefit from the 256-step resolution and the dual-channel integration that handles two independent signal paths simultaneously. Industrial calibrators, programmable power supplies, and test equipment also use the MCP4652-503E/UN to replace manual trimmer potentiometers with software-controlled adjustments.

Frequently Asked Questions
How many distinct resistance steps does MCP4652-503E/UN provide, and what is the step size on the 50 kΩ version?
The MCP4652-503E/UN provides 256 wiper positions across a 50 kΩ end-to-end resistance, giving a nominal step size of approximately 195 Ω per step (50,000 Ω ÷ 256 steps). The minimum wiper resistance is approximately 75 Ω to 195 Ω depending on supply voltage, so the effective range spans from roughly 195 Ω at the low end to 50 kΩ at the high end, suitable for fine-resolution analog adjustment in gain and bias circuits.
What I2C address options does the MCP4652-503E/UN support, and how many devices can share a single I2C bus?
The MCP4652-503E/UN uses a 7-bit I2C address with the upper 4 bits fixed at 0101 and the lower 3 bits set by the A2, A1, A0 address pins, providing up to 8 unique addresses. This means up to 8 MCP4652-503E/UN devices (16 independent 50 kΩ potentiometer channels total) can share a single 2-wire I2C bus at up to 400 kHz (Fast Mode), maximizing channel density in multichannel calibration or audio routing systems.
For a programmable gain amplifier design, how does the 2 kHz signal bandwidth of the MCP4652-503E/UN limit the application frequency range?
The MCP4652-503E/UN specifies a nominal signal bandwidth of 2 kHz for the resistor array when used in a voltage divider or gain-setting configuration. This means the device is suitable for DC to audio-frequency signals up to approximately 2 kHz with minimal attenuation. Applications above 2 kHz, such as high-frequency filter tuning or RF gain control, would see increasing signal attenuation and phase shift, making the MCP4652-503E/UN unsuitable for those frequency ranges without additional buffering.
Does the MCP4652-503E/UN retain its wiper setting after power is removed, and what does this mean for system startup behavior?
Yes. The MCP4652-503E/UN includes non-volatile memory that stores the last written wiper position. When power is restored, the device automatically loads the saved 8-bit wiper value without any I2C initialization command from the host MCU. In production calibration workflows, this means a calibrated gain or offset value set during factory test persists through power cycles, eliminating the need for the host processor to re-send configuration data at every system boot.
