(1) Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.

DESCRIPTION/ORDERING INFORMATION

The TLC2543 is a 12-bit, switched-capacitor, successive-approximation, analog-to-digital converter (ADC). This

device, with three control inputs [chip select (CS), input-output clock (I/O CLOCK), and 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 1 of 11 inputs or any 1 of 3 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.

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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
