The XL2543 is a high-speed, low-power analog-to-digital converter (ADC) with SOP20 RoHS packaging manufactured by XINLUDA. This ADC offers a wide range of features to optimize accuracy, speed, power, and conversion rate. It has a sampling rate of up to 50Msps and a conversion resolution of 16-bit monotonic. It also includes an integrated phase locked loop (PLL) for automatic clock and reference management, which allows for operation up to 200MHz. The XL2543 has an operation range from 1.8V to 5.5V and consumes only 7mW of power. Additionally, it has a selectable gain, which allows for variable input ranges and direct connection to low-level signals. Moreover, the XL2543 is RoHS compliant and offers excellent thermal performance.
