The Xinluda XD548 is an 8-bit serial analog-to-digital converter (ADC) IC built on a CMOS process using an 8-bit switched-capacitor successive-approximation (SAR) architecture. It connects to common microprocessors and controllers over a simple three-wire serial interface (CS, I/O CLOCK, and DATA OUT), making it well suited to low-cost measurement and control systems. The XD548 is supplied in a conventional through-hole DIP-8 package; a pin-compatible SOP-8 surface-mount variant is offered as the XL549.
With an on-chip sample-and-hold circuit, a built-in 4 MHz system clock, and a reference input that supports ratiometric scaling of the conversion range, the XD548 delivers stable conversions for sensing relatively small analog signals.
The XD548 is a specialty Xinluda part with limited authorized-distributor availability, which can make it difficult to source in production quantities through mainstream channels. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management ICs, data-converter ICs, and optocouplers. We help engineers and buyers secure parts like the XD548 when standard catalog stock runs dry.
Every order is backed by our commitment to authenticity, inspection, and traceability, and we ship worldwide to keep your builds on schedule. If you need the XD548 in DIP-8 (or the SOP-8 XL549 variant), request a quote today and our sourcing team will respond with availability, lead time, and pricing for your required quantity.
The XD548 is an 8-bit serial-output analog-to-digital converter (ADC) from Xinluda. It uses a CMOS switched-capacitor successive-approximation (SAR) architecture and communicates with a host microprocessor over a 3-wire serial interface (CS, I/O CLOCK, and DATA OUT).
No. Despite occasionally being mislabeled, the XD548 is an 8-bit serial SAR analog-to-digital converter, not a voltage regulator. Its datasheet confirms ADC functionality with an on-chip sample-and-hold circuit.
The XD548 is supplied in a conventional through-hole DIP-8 package. A pin-compatible SOP-8 surface-mount version is offered separately under the part number XL549.
Per the datasheet, the XD548 offers 8-bit resolution, a 4 MHz internal clock, a maximum conversion time of 17 us, a 45,500 samples/s sampling rate, total offset error of +/-0.5 LSB max, a 3 V to 6.5 V supply range, and an operating temperature range of -40 C to +85 C.
It targets low-cost measurement and control systems, including handheld and portable instruments, portable monitors and power-management subsystems, industrial signal monitoring, and general data acquisition.
The XD548 has limited authorized-distributor availability. Pacific Component Xchange is an independent distributor that sources hard-to-find ICs like the XD548. Submit a request for quote (RFQ) and our team will reply with availability, lead time, and pricing for your quantity.
