XL548 – ADC (Analog-to-Digital Converter) – Xinluda
The Xinluda XL548 is an 8-bit serial successive-approximation (SAR) analog-to-digital converter with a 3-wire serial interface, 45.5 kSPS throughput, and a 3V-6.5V operating supply range. It is pin/function compatible with the industry-standard TLC548.
The Xinluda XL548 is an 8-bit serial analog-to-digital converter (ADC) built on a switched-capacitor successive-approximation (SAR) architecture. Designed as a function-compatible alternative to the industry-standard TLC548, it delivers a simple 3-wire serial interface (CS, DATA OUT, I/O CLOCK) for easy connection to microcontrollers and microprocessors, making it a cost-effective choice for embedded measurement and monitoring designs.
With an on-chip system clock, a wide 3V to 6.5V operating supply range, and differential reference-voltage inputs, the XL548 is well suited to handheld, portable, and industrial applications where board space and power budget are constrained.
