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.
The converter incorporated in the TLC542 features differential high-impedance reference inputs that facilitate
ratiometric conversion, scaling, and isolation of analog circuitry from logic and supply noises. A switched-
capacitor design allows low-error (
±0.5 LSB) conversion in 20 s over the full operating temperature range.
The TLC542C is characterized for operation from 0
°C to 70°C and the TLC542I is characterized for operation
from – 40
°C to 85°C.
