Key Features
- Single-channel 50 kΩ digital potentiometer with 128 steps over I2C 2-wire interface for simple microcontroller integration
- Available in 5 kΩ, 10 kΩ, and 50 kΩ resistance variants sharing identical pinout and MSOP-8 package
- 2 kHz nominal bandwidth suitable for audio frequency gain control and signal level adjustment applications
Applications
The MCP4532-503E/MS is used in I2C-controlled gain stages, LCD contrast adjustment circuits, and sensor calibration trimmers where software-settable resistance replaces manual mechanical potentiometers. Its 128-step resolution across 50 kΩ provides approximately 390 Ω per step, allowing fine analog tuning in audio DSP systems and signal conditioning front-ends. The compact MSOP-8 form factor is a natural fit for space-limited industrial control modules and embedded sensor nodes.

Frequently Asked Questions
How many resistance steps does the MCP4532-503E/MS offer and what is the step resolution at 50 kΩ?
The MCP4532-503E/MS provides 128 wiper positions across a 50 kΩ end-to-end resistance, giving approximately 390 Ω per step. This resolution is sufficient for audio gain control, contrast adjustment, and sensor offset calibration where fine incremental tuning is needed.
Does the MCP4532-503E/MS retain its wiper position after power loss?
The MCP4532-503E/MS stores the wiper position in volatile SRAM, so it resets to the mid-scale position (step 64 of 128) on power-up. Applications requiring non-volatile wiper memory should instead use the MCP4532's NV variants, which retain position across power cycles using internal EEPROM.
For an I2C bus shared with multiple peripherals, how does the MCP4532-503E/MS address assignment work?
The MCP4532-503E/MS uses a fixed I2C address with the last 2 bits hardware-configured via the A0 and A1 address pins, allowing up to 4 devices on the same 2-wire bus. Each device responds independently to its unique 7-bit address, enabling 4 independent 50 kΩ channels on one I2C interface.
