Summary: ADC0820CCN, 8-Bit High Speed μP Compatible A/D Converter, 20-DIP, 10V, 1mA, National Semiconductor
Description: The ADC0820CCN is an 8-Bit high speed μP compatible A/D converter with track/hold
function. By using a half-flash conversion technique, the ADC0820CCN offers a 1.5 μs conversion time
and dissipates only 75 mW of power. The half-flash technique consists of 32 comparators, a most
significant 4-bit ADC and a least significant 4-bit ADC. The input to the ADC0820CCN is tracked and
held by the input sampling circuitry eliminating the need for an external sample-and-hold for signals
moving at less than 100 mV/μs. For ease of interface to microprocessors, the ADC0820CCN has
been designed to appear as a memory location or I/O port without the need for external interfacing
logic.
