ADC0808CCN

8-Bit Analog-to-Digital Converter with 8-Channel Multiplexer manufactured by National Semiconductor. This classic data-acquisition subsystem integrates an 8-channel analog input multiplexer, a successive-approximation A/D converter core, and microprocessor-compatible control logic onto a single 28-pin monolithic chip. It functions by sequentially addressing and sampling raw analog voltage variations from up to eight discrete external sensors, transforming those analog curves into highly accurate 8-bit digital bytes, and floating the results across a system data bus via latched tri-state outputs. It saw extensive historical deployment inside vintage automotive engine diagnostic test equipment, early environmental climate control loops, factory sensor monitoring matrices, and robotics research platforms.
