An integrated digital electronic encoder that converts mechanical movement of a device input into a signal that can be applied to particular purposes is described. The encoder and associated signal conditioning and processing circuitry are embedded together as a single unit for simplicity of assembly into particular applications, and reliability. The integrated digital electronic encoder includes a substrate with first and second substantially opposed major surfaces, and a digital encoder formed on the first major surface of the substrate. The encoder comprises an actuation shaft, and the encoder is configured to generate electrical signals in response to movement of the actuation shaft. Electronic circuitry is attached to the second major surface of the substrate, preferably suing surface mount technology. The electronic circuitry is electrically connected with the digital encoder to process the signals produced by the encoder. The electronic circuitry includes programmable logic to provide multiple function capability to the integrated digital encoder. The electronic circuitry also includes supervisory power circuitry for conditioning the power supplied to the programmable logic, and output circuitry such as a communication interface.
