description
The TLC2543 is a 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.
