description

The TLC2543C and TLC2543I are 12-bit, switched-

capacitor, successive-approximation, analog-to-

digital converters. Each device has three control

inputs [chip select (CS), the input-output clock (I/O

CLOCK), and the address input (DATA INPUT)] and

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 = 0°C to 70°C. The TLC2543I is characterized for

operation from T = –40°C to 85°C. The TLC2543M is characterized for operation from T = –55°C to 125°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
