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.
