Overview
The TLC3541IDR is a high-performance, 14-bit, low-power analog-to-digital converter (ADC) produced by Texas Instruments. This device operates from a single 5-V supply and is available in an 8-pin SOIC (D) package. It features a built-in conversion clock and supports a sampling rate of 200 KSPS. The TLC3541 is designed for low power consumption, with an auto-power down mode to further reduce power usage. It provides a high-speed serial link to modern host processors with an external SCLK up to 15 MHz, making it suitable for various industrial and measurement applications.
