The XL549 is a low-cost, single-channel 8-bit analog-to-digital converter (ADC) manufactured by Shenzhen Xinluda Information Technology Co., Ltd. (Xinluda). Supplied in a compact SOP-8 surface-mount package, the XL549 implements A/D conversion using an 8-bit switched-capacitor successive-approximation technique and interfaces to a host microprocessor or controller over a simple 3-wire serial interface (CLK, CS, DATA OUT). This makes it easy to add basic analog measurement to microcontroller-based designs.
The XL549 is the SOP-8 surface-mount counterpart to the pin-compatible DIP-8 XD549, and belongs to the same Xinluda serial-ADC family as the XL548 / XD548 devices. Functionally it follows the well-established single-channel serial ADC architecture comparable to the classic TLC549 class of converters, making it a convenient choice for cost-sensitive sensing and data-acquisition tasks.
Note: detailed electrical limits should be confirmed against the current Xinluda datasheet for the specific date/lot code supplied.
The XL549 is a specialty Xinluda part with little to no authorized-distributor stock, which makes it difficult to source through mainstream channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find, obsolete, and allocated analog and mixed-signal ICs. Our global sourcing network, supplier vetting, and authenticity/quality inspection process help you secure genuine XL549 devices even when they are unavailable elsewhere.
Pricing on this part is quote-based. Submit a Request for Quote (RFQ) with your target quantity and date-code requirements and our sourcing team will respond quickly with availability, lead time, and pricing. We support worldwide shipping and can assist with both prototype and production volumes.
The XL549 is a single-channel, 8-bit serial-output analog-to-digital converter (ADC) from Xinluda, supplied in an SOP-8 surface-mount package. It uses a 3-wire serial interface (CLK, CS, DATA OUT) and is functionally similar to classic single-channel serial ADCs such as the TLC549.
The XL549 is manufactured by Shenzhen Xinluda Information Technology Co., Ltd. (Xinluda), a Chinese semiconductor supplier. Note that Xinluda is a different company from XLSEMI, despite the similar 'XL' part prefixes.
The XL549 is offered in an 8-pin SOP-8 (small-outline) surface-mount package. The pin-compatible DIP-8 through-hole version is sold under the part number XD549.
They are the same 8-bit serial ADC in different packages: the XL549 is the SOP-8 surface-mount version, while the XD549 is the DIP-8 through-hole version. Both are single-channel 8-bit serial ADCs.
The XL549 is an 8-bit, single-channel serial ADC with a 3-wire interface, a sample rate up to 40,000 SPS, conversion time of about 17 us, a 4 MHz internal clock, differential reference input, +/-0.5 LSB total unadjusted error, and a 3 V to 6.5 V operating supply, in an SOP-8 package.
The XL549 is a hard-to-find part with little or no authorized-distributor availability, so it is offered on a Request-for-Quote (RFQ) basis. Pacific Component Xchange can source it through its independent supplier network; submit an RFQ with your quantity for current availability, lead time, and pricing.
