NXP Semiconductors ADC0820
the ADC0820 is tracked and held by the input sampling circuitry, eliminating the need for an external sample-and-hold for signals slewing at less than 100mV/µs. For ease of interface to microprocessors, the ADC0820 has been designed to appear as a memory location or I/O port without the need for external interfacing logic.| Part No. | ADC0820 |

DESCRIPTION
By using a half-flash conversion technique, the 8-bit ADC0820 CMOS A/D offers a 1.5µs conversion time while dissipating a maximum 75mW of power. The half-flash technique consists of 31 comparators, a most significant 4-bit ADC and a least significant 4-bit ADC.
