The ADC0809CCN is an 8‑bit analog‑to‑digital converter (ADC) with an integrated 8‑channel multiplexer, designed for interfacing multiple analog signals with digital systems. It converts analog inputs into 8‑bit digital outputs using a successive approximation register (SAR) architecture, ensuring reliable and accurate conversion. Widely used in sensor interfacing, instrumentation, automation, and educational projects, the ADC0809CCN is compatible with popular microcontrollers such as 8051, PIC, AVR, and Arduino.
