ADC0820 A/D Converter

By using a half-flash conversion technique, the 8-bit ADC0820 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. The input to the ADC0820 is tracked and held.
