This device features a rheostat configuration with 129 taps, offering a high level of granularity in resistance adjustment. The MCP4632T-103E/MF operates within a supply voltage range of 1.8V to 5.5V, making it suitable for various power supply environments. It boasts a resistance of 10kΩ with a tolerance of ±20%, ensuring reliable performance across different operating conditions. The device is equipped with a linear taper, providing a consistent and predictable change in resistance as the tap position is adjusted.

MCP4632T-103E/MF Features

The MCP4632T-103E/MF offers several unique features that set it apart from similar models in the market. One of its standout characteristics is the selectable address feature, which allows multiple devices to be connected on the same I2C bus without address conflicts. This feature is particularly beneficial in complex systems where multiple digital potentiometers are required. The device also features a volatile memory type, meaning the resistance setting is maintained as long as power is supplied but resets to a default value upon power loss. This can be advantageous in applications where a known initial state is required.

The MCP4632T-103E/MF has a temperature coefficient of 150ppm/°C, ensuring stable performance over a wide temperature range. It also has a low wiper resistance of 75Ω, which minimizes the impact of the wiper on the overall resistance. The device is packaged in a 10-lead DFN package, which is suitable for surface mount applications and provides a compact footprint for space-constrained designs. Additionally, the MCP4632T-103E/MF is REACH unaffected and RoHS3 compliant, ensuring it meets environmental and regulatory standards.
