Overview
The ADC0820CCM is a high-speed, microprocessor-compatible, 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component utilizes a half-flash technique to achieve a conversion time of 1.4 μs, making it suitable for applications requiring rapid data conversion. The ADC operates on a single +5V supply and has an analog input range of 0V to +5V. It also features a built-in track-and-hold function, eliminating the need for an external track-and-hold circuit for input slew rates up to 100 mV/μs.
