Vishay Intertechnology has broadened its optoelectronic portfolio with the introduction of what it claims is the industry's first signal conditioning ICs suitable for processing IR remote control signals from discrete photodiodes. Offered in small QFN packages measuring 2x2x0.76mm, the VSOP383xx and VSOP584xx families are capable of processing continuous data transmission and feature a wide supply voltage range and low supply current. By separating the signal processing circuit from the photodiode and packaging it in a QFN package, the ICs are claimed to provide greater flexibility for a number of diverse applications. For example, they will be used in systems where ultra-wide spatial reception is required through multiple photodiodes, aimed in different directions. They will also be used where alternative wavelengths need to be received, such as blue light in under-water applications.
