VSOP383xx Preamplifier Circuits

The Vishay VSOP383xx series of preamplifier circuits feature Cyllene 2 ICs, which are ideal for infrared (IR) remote control applications. Offered in a 2 mm by 2 mm by 0.76 mm QFN package, the enhanced solutions provide drop-in, plug-and-play replacements for existing devices in the series while offering a wide supply voltage range from 2.0 V to 5.5 V, 37% higher dark-ambient sensitivity, and improved performance under strong DC light and Wi-Fi noise. By upgrading the VSOP383xx series with their in-house IC technology, Vishay ensures the long-term availability of their products with reduced lead times for their customers. As drop-in replacements for existing solutions, with no mechanical differences and similar electrical characteristics, the devices help save costs by eliminating the need for PCB redesigns. With less susceptibility to EMI from 2.4 GHz and 5 GHz frequencies, which can cause unwanted output pulses, the preamplifier circuits can be placed near Wi-Fi antennas for increased design flexibility, while their robustness under bright sunlight enables outdoor use.
