description
The TLC532A and TLC533A are monolithic
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
