The ADC0804 is a classic 8‑bit analog‑to‑digital converter (ADC) designed for microcontroller and embedded system applications. It converts analog input signals into an 8‑bit digital output, making it ideal for interfacing sensors, instrumentation, and control systems. With its successive approximation architecture, the ADC0804 offers reliable performance, simple interfacing, and compatibility with popular microcontrollers such as 8051, PIC, AVR, and Arduino. It is widely used in educational projects, industrial automation, and embedded electronics.
