Miniature automatic gain control assorted infrared receiver AGC5

Recently, Vishay Intertechnology, Inc. announced that the company's optoelectronic product portfolio has added a complete series of miniature automatic gain control class 5 (AGC5) infrared receivers for remote control systems - AGC5. Vishay's AGC5 devices are suitable for short pulse coding, have excellent noise suppression capabilities, and can achieve the best reception distance under noisy conditions.

　　Vishay's AGC5 device has no effect on dim LCD backlights, plasma screen noise, any fluorescent lighting, or the major source of ambient light noise that severely affects infrared system performance.

　　With improved immunity to ambient light and insensitivity to supply voltage ripple and noise, these infrared receivers are optimized for remote control applications in industrial and consumer products such as set-top boxes, LCD TVs and DVD players, where stable transmission distance and clean signals in the presence of optical noise are extremely important.

　　Each receiver includes a photodetector and preamplifier circuit mounted in an epoxy-sealed module. The transparent module can be used as an infrared lens. The AGC5 receiver can operate at a supply voltage of 2.5V to 5.5V, and the minimum radiant illumination is 0.1 to 0.15mW/m2, depending on the package. This means that most standard remote controls can transmit up to 45 meters in a dark environment. The module's carrier frequency range is 30kHz to 56kHz, and the supply current is as low as 0.35mA, which complies with RoHS 2002/95/EC and WEEE 2002/96/EC specifications.
