Interfacing the TLC2543 ADC to the TMS320C25 DSP
Texas InstrumentsThis document details an interface between a TMS320C25 digital signal processor (DSP) and the TLC2543 12-bit 11-channel analog-to-digital converter (ADC). A description of the TLC2543 hardware interfacing and a software description are provided. Benchmark information for sample rates data timing and control timing are provided. Briefly discussed are the benefits in compensators or feedback sy
DC-to-DC Converter Noise Reduction
Texas InstrumentsThe inherent switching inside the DC-to-DC converter gives rise to potential sources of noise. This noise manifests itself on the output voltage as spikes at the switching frequency. Due to size and cost requirements internal filtering is limited but usually adequate for most applications. When excessive noise is suspected you must rule out extraneous noise sources.
