XL549 – Analog-to-Digital Converter (ADC) – Xinluda

The XL549 from Xinluda is a single-channel, 8-bit serial-output analog-to-digital converter (ADC) in an SOP-8 package, functionally comparable to classic TLC549-style 8-bit serial ADCs. Available for RFQ at Pacific Component Xchange.

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.

Key Features

• Single-channel (1-input) analog-to-digital converter
• 8-bit resolution
• 3-wire serial interface (CLK, CS, DATA OUT) to microprocessors/controllers
• Differential high-impedance reference input (REF+ / REF-) for ratiometric measurement of small signals
• Sample rate up to 40,000 samples per second (40 kSPS)
• Conversion time of approximately 17 us (max)
• On-chip 4 MHz typical internal system clock, independent of the external I/O clock
• Total unadjusted error of +/-0.5 LSB (max)
• Wide operating supply voltage of 3 V to 6.5 V
• Electrical characteristics specified over -40 °C to +85 °C (per datasheet electrical table)
• SOP-8 surface-mount package

Note: detailed electrical limits should be confirmed against the current Xinluda datasheet for the specific date/lot code supplied.

Applications

• Microcontroller-based sensor data acquisition
• Low-cost analog measurement and monitoring
• Handheld and portable instrumentation
• Battery, voltage, and temperature sensing front ends
• General-purpose embedded measurement and control boards

Why Source XL549 from Pacific Component Xchange

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.
