About this product
TLC1543C is a CMOS 10-bit successive-approximation analog-to-digital converter with 11 analog input channels, controlled over a simple 4-wire serial interface. It lets one microcontroller port read several sensor voltages, and includes built-in self-test modes and an end-of-conversion output.

Frequently asked questions
How do I connect the TLC1543C to a microcontroller?
Connect CS, I/O CLOCK, ADDRESS and DATA OUT to the microcontroller. The 4-bit channel address is shifted in on ADDRESS while the conversion result is shifted out on DATA OUT.
Does the TLC1543C need a reference voltage?
Yes. The conversion range is set by the reference inputs (REF+ and REF-), so a stable reference voltage must be applied to them.
