Product Summary

The ADC0820CCWM is an 8-Bit High Speed μP Compatible A/D Converter with Track/Hold Function. By using a half-flash conversion technique, the ADC0820CCWM CMOS A/D 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. For ease of interface to microprocessors, the ADC0820CCWM has been designed to appear as a memory location or I/O port without the need for external interfacing logic.
