Overview
The TLC2543IN is a 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. It is part of the TLC2543 series, which includes the TLC2543C, TLC2543I, and TLC2543M, each with different operating temperature ranges. The TLC2543IN is characterized for operation from –40°C to 85°C, making it suitable for a wide range of applications requiring high accuracy and reliability.
This ADC features a switched-capacitor, successive-approximation architecture and includes a 14-channel multiplexer that can select any one of 11 analog inputs or three internal self-test voltages. It also incorporates an inherent sample-and-hold function and an on-chip system clock, facilitating high-speed data transfers.
