Overview
Description
The TLC2543IDW is a 12-bit, 11-channel analog-to-digital converter (ADC) from Texas Instruments. It features serial communication (SPI-compatible) for easy interfacing with microcontrollers. Key characteristics include:
- Resolution: 12-bit (up to 4096 steps).
- Input Channels: 11 single-ended or 6 pseudo-differential.
- Conversion Speed: Up to 66 kSPS (10 µs max).
- Supply Voltage: 2.7V to 5.5V, making it suitable for low-power applications.
- Package: SOIC-20 (DW).
It includes an on-chip sample-and-hold and offers programmable power-down modes for energy efficiency. The TLC2543IDW is commonly used in data acquisition, industrial control, and sensor interfacing.
Its SPI-like interface simplifies integration, requiring only CLK, DIN, DOUT, and CS pins for communication. The device also supports auto-calibration for improved accuracy.
