It provides accurate precision adjustment and can be used to save system settings.

MCP4014T-103E/OT Features

The MCP4014T-103E/OT features an 8-bit Resolution and 256 steps in a 10KΩ/100KΩ resistance range. It also has 10-bit Nonvolatile Memory which enables settings to be written to it and contained even after power down. It functional temperature range is -55ºC to 125ºC and it uses an industry standard 7 No-Connect Terminal of 0.3 inch (7.6mm) centerline.

MCP4014T-103E/OT Applications

The MCP4014T-103E/OT can be used for a wide range of applications for data acquisition. It can be used for audio applications as it allows gain adjustment to be made by controlling the gain of a stage by varying the potentiometer resistance with a digital interface. Features such as its 8-bit resolution, 10-bit memory and its wide temperature range make it suitable for many other applications as well. These include time-based offset control, fine tuning PID settings, general signal conditioning, and LED calibration.

MCP4014T-103E/OT Working Principle

The MCP4014T-103E/OT is an electrically controlled resistor (ECR) that works on the principle of controlling resistance using the electrical connection to the wiper position. The resistance is set by a set of instructions given through a digital input interface. The instructions allow the wiper to be set to its ‘ home position’, and or consecutive steps along it’s full range of resistance. It also features a nonvolatile memory, allowing it to remember any settings applied to it.

Conclusion

The MCP4014T-103E/OT is an ideal solution for a variety of data acquisition applications due to its high level of repeatability, wide temperature range, 10-bit nonvolatile memory, and 8-bit resolution. It can be used to provide accurate precision adjustment and is suitable for audio applications as well as time-based offset control, fine tuning PID settings, general signal conditioning, and LED calibration.
