Analog-to-digital converter

摘要: An analog-to-digital converter includes a sample and hold circuit for sampling holding an input analog signal outputting voltage, selection code generator generating corresponding to operation mode number of conversion bits samples, decoder enable the code, comparator comparing external voltage with digital value, data register storing value final digital-to-analog by inputting reference stored in ADR, multiplexer selecting path selected generator, shift determining registers counter counting shifts multiplexer, output detector detecting lowest bit end register, controller controlling A/D clock response signal.
