- 256-position 50 kΩ digital potentiometer with 2-wire I2C interface for simple 2-pin bus connection to any microcontroller
- Non-volatile wiper position memory retains resistance setting through power loss without host firmware overhead
- Wide supply range from 2.7 V to 5.5 V in a compact 8-pin MSOP package for battery-powered gain and bias circuits
Applications
MCP4552-503E/MS is used in audio equipment for programmable equalization and volume control, replacing mechanical 50 kΩ potentiometers with digitally adjustable equivalents controlled over I2C. In precision analog front-ends, it provides bias adjustment for op-amp stages and sensor offset trimming across 256 steps without physical access to the PCB. The 8-pin MSOP package fits compact IoT sensor nodes requiring field-configurable gain settings stored across power cycles.

Frequently Asked Questions
How many wiper positions does MCP4552-503E/MS support, and what resistance increment does each step represent?
The MCP4552-503E/MS provides 256 wiper positions across a 50 kΩ end-to-end resistance, giving approximately 196 Ω per step. This resolution is sufficient for audio tone control and analog gain trimming applications where the 2 kHz bandwidth covers audio frequencies, and the non-volatile EEPROM stores the last position so the potentiometer resumes the correct setting after a power cycle without host re-initialization.
What I2C interface does the MCP4552-503E/MS use, and how does this reduce wiring complexity compared to SPI potentiometers?
MCP4552-503E/MS uses a 2-wire I2C serial interface, requiring only SDA and SCL lines shared across multiple devices on the same bus. This reduces wiring from the 4 pins needed for SPI (MOSI, MISO, SCK, CS) to just 2 pins, allowing up to 8 MCP4552 devices to share a single I2C bus at addresses configurable via A0 and A1 pins, saving PCB routing space in multi-channel audio and control systems.
How does MCP4552-503E/MS compare to MCP4552 5kΩ and 10kΩ variants when selecting for an audio equalizer circuit?
MCP4552-503E/MS provides 50 kΩ end-to-end resistance ideal for audio equalizer circuits with typical op-amp feedback networks targeting 20 kΩ to 100 kΩ impedance levels, minimizing op-amp loading distortion. The 5 kΩ variant (MCP4552-502E) causes higher op-amp loading and increased power draw, while the 10 kΩ variant limits feedback attenuation depth for notch filters. The 50 kΩ version operating at 2.7 V to 5.5 V suits both 3.3 V digital audio DSP boards and legacy 5 V analog mixers.
