Overview
The ADC0820CCN+ is a high-speed, microprocessor-compatible, 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device utilizes a half-flash technique to achieve a conversion time of 1.4 μs, making it suitable for high-speed applications. It features a built-in track-and-hold function, eliminating the need for an external track-and-hold for input slew rates up to 100 mV/μs. The ADC0820CCN+ is designed to easily interface with microprocessors, appearing as a memory location or I/O port without the need for external interfacing logic.
