Overview
The TLC2543IDBR is a 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the TLC2543 series, which includes the TLC2543C, TLC2543I, and TLC2543M, each characterized by different operating temperature ranges. The TLC2543IDBR is specifically designed for operation from –40°C to 85°C, making it suitable for a wide range of applications requiring high precision and reliability.
The TLC2543IDBR features a switched-capacitor, successive-approximation architecture and includes a 14-channel multiplexer that allows selection from 11 analog input channels or three internal self-test voltages. It also incorporates an inherent sample-and-hold function and provides high-speed data transfers through a serial 3-state output.
