LinCMOS peripheral integrated circuits each  
designed to interface a microprocessor for analog  
data acquisition. These devices are complete  
peripheral data acquisition systems on a single  
chip and can convert analog signals to digital data  
from up to 11 external analog terminals. Each  
device operates from a single 5-V supply and  
contains a 12-channel analog multiplexer, and  
8-bit ratiometric analog-to-digital (A/D) converter,  
a sample-and-hold circuit, three 16-bit registers,  
and microprocessor-compatible control circuitry.  
Additional features include a built-in self-test,  
sixmultipurpose (analog or digital) inputs, five  
external analog inputs, and an 8-pin input/output  
(I/O) data port. The three on-chip data registers  
store the control data, the conversion results, and  
the input digital data that can be accessed via the  
microprocessor data bus in two bytes
