The ADC0820 is an 8-bit CMOS analog-to-digital converter designed for microprocessor compatibility. It utilizes a half-flash technique to achieve a fast conversion time of 1.4 microseconds and includes a built-in track-and-hold function, eliminating the need for external circuitry in many applications.
The device operates from a single +5V supply and features an analog input range of 0V to +5V. It is available in various packages including Small Outline (SO), DIP, CERDIP, and Dice form factors. The datasheet provides absolute maximum ratings, electrical characteristics, timing diagrams for different operating modes (RD Mode, WR-RD Mode, Stand-Alone), and pin descriptions.
