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.
The XD2543N is a specialty Xinluda part with limited authorized-distributor availability, and the DIP-20 through-hole variant in particular can be difficult to locate through mainstream channels. Pacific Component Xchange specializes in sourcing hard-to-find and obsolete data converters, power-management ICs, and optocouplers for engineers and procurement teams worldwide. We support full traceability and authenticity verification, offer global shipping, and respond quickly to quote requests.

The XD2543N is a 12-bit, 11-channel switched-capacitor successive-approximation analog-to-digital converter (ADC) from Xinluda, supplied in a through-hole DIP-20 package with a serial three-state output interface.
They are the same ADC in different packages. Per Xinluda's product listing, the XD prefix denotes the through-hole DIP-20 version (XD2543N), while the XL prefix denotes the surface-mount SOP-20 version (XL2543). Both are 12-bit, 11-channel devices with the same core electrical specifications.
Yes. The XD2543N is functionally compatible with the industry-standard Texas Instruments TLC2543 12-bit serial ADC, making it a viable second source for existing TLC2543-based designs.
The XD2543N operates from a single 4.5 V to 5.5 V supply over an industrial temperature range of -40 C to +85 C.
The XD2543N is a specialty Xinluda data converter with limited authorized-distributor coverage, and the DIP-20 through-hole variant is less commonly stocked than its SOP-20 sibling. Pacific Component Xchange sources hard-to-find parts like this on request.
