During his rotation in Automotive, David began work on a car amplifier design to give him complete control over his car audio system. He intended to use this system as a test-bed for new signal processing techniques and system designs. The resulting circuit he designed was based on an Analog Devices ADSP-21262 DSP and a Flashcat USB programmer that could easily reprogram the amplifier. David’s final design had 6 differential speaker outputs, one LED indicator, 2 button inputs, 3 line level differential inputs, and 2 car microphone inputs.
David finished his schematic design, and created several custom footprints to supplement the layout library of his design tool. He is in the process of doing a multilayer board layout.
