description

The TLC542 is a CMOS converter built around an

8-bit switched-capacitor successive-approximation

analog-to-digital converter. The device is designed

for serial interface to a microprocessor or peripheral

via a 3-state output with three inputs [including I/O

CLOCK, CS (chip select), and ADDRESS INPUT].

The TLC542 allows high-speed data transfers and

sample rates of up to 40,000 samples per second.

In addition to the high-speed converter and

versatile control logic, an on-chip 12-channel

analog multiplexer can sample any one of 11 inputs or an internal “self-test” voltage, and the sample and hold

is started under microprocessor control. At the end of conversion, the end-of-conversion (EOC) output pin goes

high to indicate that conversion is complete. Detailed information on interfacing to most popular

microprocessors is readily available from the factory.
