The MCP40D18T-503E/LT from Microchip Technology is a 7-bit digital potentiometer offering 128 steps of resolution and a nominal resistance of 50kΩ. It supports I²C communication for control and features a wide operating voltage range from 1.8V to 5.5V.
This device is designed for potentiometer or rheostat configurations, providing zero scale to full scale wiper operation. It boasts low power consumption with a typical static current of 2.5 µA and a wide bandwidth operation of 2 MHz for the 5.0 kΩ device. The temperature coefficient is typically 15 ppm/°C for potentiometer configuration and 50 ppm/°C for rheostat configuration.
Packaged in a small SC-70-6 surface-mount package, the MCP40D18T-503E/LT is suitable for space-constrained applications. It operates across an extended temperature range of -40°C to +125°C. The device has a power-on default wiper setting at mid-scale and includes brown-out reset protection.
Applications for this digital potentiometer include amplifier gain control, sensor calibration, set point trimming, and as a cost-effective replacement for mechanical trim pots. Its I²C interface simplifies integration into various embedded systems.
