ADC0800 8-Bit A/D Converter

General Description

Features

Low cost

The ADC0800 is an 8-bit monolithic A/D converter using P-

channel ion-implanted MOS technology. It contains a high

input impedance comparator, 256 series resistors and ana-

log switches, control logic and output latches. Conversion is

5V, 10V input ranges

No missing codes

Ratiometric conversion

TRI-STATE outputs

Fast

performed using

a successive approximation technique

where the unknown analog voltage is compared to the re-

sistor tie points using analog switches. When the appropri-

ate tie point voltage matches the unknown voltage, conver-

sion is complete and the digital outputs contain an 8-bit

complementary binary word corresponding to the unknown.

Contains output latches

TTL compatible
