description
The TLC2543C and TLC2543I are 12-bit, switched-
capacitor, successive-approximation, analog-to-
digital converters. Each device, with three control
inputs [chip select (CS), the input-output clock, and
the address input (DATA INPUT)], is designed for
communication with the serial port of a host processor
or peripheral through a serial 3-state output. The
device allows high-speed data transfers from the
host.

In addition to the high-speed converter and versatile control capability, the device has an on-chip 14-channel
multiplexer that can select any one of 11 inputs or any one of three internal self-test voltages. The
sample-and-hold function is automatic. At the end of conversion, the end-of-conversion (EOC) output goes high
to indicate that conversion is complete. The converter incorporated in the device features differential
high-impedance reference inputs that facilitate ratiometric conversion, scaling, and isolation of analog circuitry
from logic and supply noise. A switched-capacitor design allows low-error conversion over the full operating
temperature range.
The TLC2543C is characterized for operation from T_A = 0°C to 70°C. The TLC2543I is characterized for
operation from T_A = – 40°C to 85°C. The TLC2543M is characterized for operation from T_A = – 55°C to 125°C.
