ADC0803 and ADC0805  
description  
The ADC0803 and ADC0805 are CMOS 8-bit, successive-approximation, analog-to-digital converters that use  
a modified potentiometric (256R) ladder. These devices are designed to operate from common microprocessor  
control buses with the 3-state output latches driving the data bus. The devices can be made to appear to the  
microprocessor as a memory location or an I/O port. Detailed information on interfacing to most popular  
microprocessors is readily available from the factory.  
A differential analog voltage input allows increased common-mode rejection and offset of the zero-input analog  
voltage value. Although a reference input (REF/2) is available to allow 8-bit conversion over smaller analog  
voltage spans or to make use of an external reference, ratiometric conversion is possible with the REF/2 input  
open. Without an external reference, the conversion takes place over a span from V  
to ANLG GND. The  
CC  
devices can operate with an external clock signal or with an additional resistor and capacitor, using an on-chip  
clock generator.  
The ADC0803C and ADC0805C are characterized for operation from 0°C to 70°C. The ADC0803I and  
ADC0805I are characterized for operation from –40°C to 85°C.
