Digital Potentiometers

MCP41050T-I/SN Description

The MCP41050T-I/SN is a digital potentiometer manufactured by Microchip Technology, featuring a 50kOhm resistance with 256 taps. This surface-mount device operates within a supply voltage range of 2.7V to 5.5V and is compliant with the RoHS3 standard. It is designed with a linear taper and a typical temperature coefficient of 800ppm/°C. The MCP41050T-I/SN is a volatile memory type device, which means that its settings will be lost when power is removed. It is packaged in a tape and reel format and is classified under the HTSUS code 8542.39.0001.

MCP41050T-I/SN Features

• Interface: The MCP41050T-I/SN uses a SPI interface, which is a common and efficient method for communication in digital systems.
• Tolerance: It offers a tolerance of ±30%, which is typical for digital potentiometers and provides a reasonable range for adjustments.
• Number of Circuits: With a single circuit, it is suitable for applications requiring a single variable resistor.
• Memory Type: Being volatile, it is ideal for applications where the potentiometer's setting does not need to be retained when power is off.
• REACH Status: The device is REACH unaffected, indicating compliance with European chemical regulations.
• Moisture Sensitivity Level (MSL): Rated at level 1, it has unlimited storage time before baking is required, which is beneficial for handling and storage.

MCP41050T-I/SN Applications

The MCP41050T-I/SN is ideal for applications where precise digital control over resistance is needed. Some specific use cases include:

• Audio Equipment: For adjusting volume or tone controls in digital audio devices.
• Industrial Controls: To fine-tune sensor thresholds or setpoints in industrial automation systems.
• Consumer Electronics: In devices like thermostats or lighting controls where user-adjustable settings are required.
• Test and Measurement Equipment: For calibrating equipment or as part of a variable resistance network.

Conclusion of MCP41050T-I/SN

The MCP41050T-I/SN stands out for its ease of integration into digital systems due to its SPI interface and its broad supply voltage range. Its linear taper and 256 taps provide a high degree of precision for resistance adjustments. The volatile memory characteristic makes it suitable for applications where settings do not need to be persistent. Overall, the MCP41050T-I/SN is a robust choice for digital potentiometer applications in various industries, offering a balance of performance, flexibility, and reliability.
