The MCP40D18T-104E/LT from Microchip Technology is a 7-bit digital potentiometer offering 128 discrete resistance steps. It is configurable as a rheostat with a nominal resistance of 100 kΩ and a tolerance of ±20%. The device utilizes an I2C interface for control and operates within a wide voltage range of 1.8V to 5.5V.
Key electrical characteristics include a low wiper resistance of 100 Ω typical and a temperature coefficient of 15 ppm/°C typical for potentiometer configuration. It supports a bandwidth of 2 MHz typical for the 5.0 kΩ device. The static current consumption is a low 2.5 µA typical, making it suitable for power-sensitive applications.
This digital potentiometer is housed in a compact SC-70-6 surface-mount package. Its features make it a cost-effective replacement for mechanical trim pots in applications such as amplifier gain control, sensor calibration, and set point trimming.
