Key Features
- Single-channel 7-bit resolution with 128 wiper positions and 5 kΩ end-to-end resistance (502 code), enabling fine-grained programmable resistance adjustment over I2C from a host microcontroller
- 2-wire I2C serial interface with up to 8 addressable devices on one bus, allowing multiple potentiometers to share the same 2-wire bus without GPIO multiplexing
- Low-power CMOS design operating from 2.7 V to 5.5 V with standby current under 1 µA, suitable for battery-powered portable and wearable devices
Applications
The MCP4552-502E/MS is used wherever a digitally adjustable resistance is needed, such as programmable gain amplifier stages, LCD contrast or brightness control, sensor calibration offset trimming, and audio volume control circuits. Its I2C interface makes it straightforward to integrate into any microcontroller-based system, allowing run-time or factory calibration without mechanical trimmer potentiometers. The compact 8-pin MSOP footprint suits portable medical devices, industrial handheld instruments, and consumer IoT nodes requiring software-controlled analog tuning.

Frequently Asked Questions
What resistance value and resolution does the MCP4552-502E/MS offer?
The MCP4552-502E/MS provides a 5 kΩ end-to-end resistance (the '502' in the part number denotes 5 kΩ) with 7-bit resolution giving 128 discrete wiper tap positions, resulting in approximately 39 Ω per step for fine-grained programmable resistance in gain or bias-setting circuits.
How is the MCP4552-502E/MS controlled and how many devices can share the same bus?
The device uses a 2-wire I2C serial interface operating at standard 100 kHz and fast-mode 400 kHz clock speeds. Up to 8 MCP4552 devices can be addressed independently on a single I2C bus by configuring the 3 hardware address pins (A0–A2), avoiding the need for additional chip-select lines.
What supply voltage range and quiescent current does MCP4552-502E/MS require?
The MCP4552-502E/MS operates from a 2.7 V to 5.5 V single supply, drawing a typical quiescent current of only 1 µA in standby mode. This ultra-low power characteristic makes it ideal for always-on battery-operated systems such as wearable sensors and handheld meters.
In which circuit configurations can the MCP4552-502E/MS replace a mechanical trimmer potentiometer?
The device can replace mechanical trimmers in voltage dividers, op-amp feedback networks for programmable gain from 1 V/V to over 100 V/V, RC filter cutoff-frequency tuning, and DAC output scaling circuits—wherever a 5 kΩ adjustable resistor with 128 positions and software control is more reliable than a manual mechanical adjustment that may drift over -40°C to +125°C temperature cycles.
