By using a half-flash conversion technique, the 8-bit ADC0820-N CMOS A/D offers a 1.5 µs conversion time and dissipates only 75 mW of power. The halfflash technique consists of 32 comparators, a most significant 4-bit ADC and a least significant 4-bit ADC. The input to the ADC0820-N is tracked and held by the input sampling circuitry eliminating the need for.
