XL1543 – Analog-to-Digital Converter (ADC) – Xinluda

The XL1543 is a serial analog-to-digital converter (ADC) from XINLUDA, part of its serial ADC line and equivalent to the industry-standard TLC1543. This is a hard-to-find, request-for-quote part sourced through Pacific Component Xchange.

The XL1543 is a serial analog-to-digital converter (ADC) from XINLUDA (Shenzhen Xinluda Information Technology Co., Ltd.), a Chinese semiconductor maker whose catalog includes logic, interface, amplifier, and data-converter devices that are pin-and-function equivalents of long-running industry-standard parts. The XL1543 is offered as a drop-in equivalent of the well-known Texas Instruments TLC1543 10-bit, 11-channel serial ADC, and sits alongside the XINLUDA XL2543 (a 12-bit TLC2543 equivalent) in the company’s data-converter line. It is not stocked by authorized franchise distributors of the original-brand part, making it a genuinely hard-to-find option for engineers maintaining existing designs or building to a fixed bill of materials.

Key Features

• Manufacturer: XINLUDA (Shenzhen Xinluda Information Technology Co., Ltd.)
• Switched-capacitor successive-approximation serial ADC
• Functional equivalent of the industry-standard TLC1543 (10-bit, 11-channel serial ADC)
• Multiplexed analog inputs with serial (SPI-compatible) host interface
• Member of the XINLUDA serial data-converter family (alongside the XL2543 12-bit ADC)

Exact electrical ratings (supply voltage range, resolution, channel count, conversion/sample rate, and the precise package body) for the XL1543 are confirmed only against the original XINLUDA datasheet. To avoid publishing unverified figures, the verified ratings are supplied with each quotation along with the manufacturer datasheet for your specific date and lot code.

Applications

• Data acquisition and multi-channel sensor sampling
• Industrial control and automation measurement
• Embedded microcontroller systems requiring serial ADC input
• Instrumentation and process monitoring
• Consumer and appliance electronics with analog sensing

Why Source XL1543 from Pacific Component Xchange

Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete analog, data-converter, and interface ICs. Because the XL1543 has little to no authorized-distributor availability outside of regional channels, sourcing it reliably requires a partner with deep access to the global supply chain. We help engineering and procurement teams locate scarce XINLUDA inventory, verify authenticity, and ship worldwide.

• Hard-to-find and obsolete sourcing for XINLUDA parts not carried by Western franchise distributors
• Authenticity verification and quality screening to protect against counterfeit risk
• Global shipping with flexible quantities to match your build schedule

Request a quote (RFQ) for the XL1543 today and our sourcing team will confirm availability, pricing, lead time, and the verified manufacturer datasheet for your requirement.
