Overview
The ADC0809CCV is an 8-bit analog-to-digital converter (ADC) produced by National Semiconductor, now part of Texas Instruments. This monolithic CMOS device integrates an 8-bit ADC, an 8-channel multiplexer, and microprocessor-compatible control logic. It uses the successive approximation technique for conversion and features a high impedance chopper stabilized comparator, a 256R voltage divider with analog switch tree, and a successive approximation register. The device is designed to eliminate the need for external zero and full-scale adjustments, making it highly versatile and efficient.
