XD2543N – 12-Bit Serial ADC – Xinluda

The Xinluda XD2543N is a 12-bit, 11-channel switched-capacitor successive-approximation analog-to-digital converter with a serial output interface, housed in a through-hole DIP-20 package. It is the DIP-20 counterpart of the SOP-20 XL2543 and is functionally compatible with the industry-standard TLC2543.

The Xinluda XD2543N is a 12-bit, switched-capacitor, successive-approximation analog-to-digital converter (ADC) featuring an 11-channel input multiplexer and a three-state serial output interface. Supplied in a through-hole DIP-20 package, the XD2543N is the through-hole counterpart to the surface-mount SOP-20 XL2543, sharing the same core function and electrical characteristics. The device is a functional equivalent of the widely deployed Texas Instruments TLC2543, making it a practical second source for legacy and cost-sensitive designs.

With an on-chip sample-and-hold, a serial port that interfaces directly to host microcontrollers and DSPs, and operation from a single 4.5 V to 5.5 V supply, the XD2543N is well suited to multi-channel data-acquisition tasks in industrial and consumer equipment.

Key Features

• 12-bit resolution, switched-capacitor successive-approximation architecture
• 11 multiplexed analog input channels
• Serial three-state output interface with programmable MSB/LSB-first output and selectable output data length
• Single-supply operation from 4.5 V to 5.5 V
• On-chip sample-and-hold and differential reference inputs
• Through-hole DIP-20 package
• Operating temperature range: -40 C to +85 C
• Functionally compatible with the TLC2543 / XL2543 (SOP-20)

Applications

• Multi-channel industrial data acquisition and process monitoring
• Sensor signal digitization (temperature, pressure, position)
• Programmable logic controllers and instrumentation
• Battery and power monitoring systems
• Consumer and white-goods control boards
• Legacy TLC2543-based designs requiring a functional replacement
