Description
The ADC0808CCN is a sophisticated, microprocessor-compatible 8-bit Analog-to-Digital Converter (ADC) that integrates an 8-channel analog multiplexer, making it a powerful solution for multi-sensor data acquisition systems. Utilizing the proven Successive Approximation Register (SAR) conversion technique, this device features a high-impedance, chopper-stabilized comparator and a high-precision 256R voltage divider, ensuring reliable and accurate signal conversion without the requirement for external zero or full-scale adjustments.
Engineered for seamless integration into embedded systems, the ADC0808 offers latched and decoded multiplexer address inputs alongside latched TTL TRI-STATE outputs for straightforward microprocessor interfacing. Its optimized design combines high speed, excellent long-term repeatability, and low power consumption (15 mW), making it perfectly suited for demanding industrial automation, process control, and complex signal processing applications. The robust 28-pin PDIP package is specifically designed for ease of use in educational labs, breadboard prototyping, and standard through-hole PCB assembly.
