Product specification  
8-Bit, high-speed, µP-compatible A/D converter  
with track/hold function  
ADC0820  
DESCRIPTION  
PIN CONFIGURATION  
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.

The input to 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.
