Description
Introduction to TLC1543CFNR
- The TLC1543CFNR is a Texas Instruments CMOS analog-to-digital converter (ADC) in the TLC1543 family. It is designed for low‑power, moderate‑speed data acquisition with microcontrollers.
- Interface and operation: It supports a multi‑plexed analog input, delivering an 8‑bit digital word on a parallel data bus. It requires an external clock and a start signal; End‑of‑Conversion (EOC) indicates when data is ready. A reference voltage sets full‑scale.
- Packaging: CFNR is TI’s packaging code for this device variant.
- Typical use: Reading sensors or other analog signals in microcontroller projects, instrumentation, and control systems.
- Quick usage notes: Choose Vref, connect inputs to the multiplexer, provide clock, assert start, then read D0–D7 when EOC asserts.
- Important: For exact electrical specs (SPS, input range, timing, pinout), consult the official TLC1543CFNR datasheet.
