Malvern, Pa.In a move to minimize the impact of fluorescent lamps (CFLs) and other disturbance signals on IR remote control systems, Vishay Intertechnology Inc. released five series of high-sensitivity IR receivers the TSOP313, TSOP323, TSOP343, TSOP383 and TSOP393.
As AGC3 devices, the receivers are optimized for noisy environments and short burst codes.
The TSOP313, TSOP323, TSOP343, TSOP383, and TSOP393 series of ultra-noise-resistant AGC3 IR remote control receivers provide robustness against all disturbance signals and better suppress spurious pulses from energy-saving fluorescent lamps.
With a high resistance to ESD, as well as improved shielding against EMI and immunity against ambient light, the IR receivers are optimized for remote control, data transmission, and light barrier applications in TV sets, cable boxes, satellite receiver boxes, DVD players, audio systems, air conditioners, and toys.
Each receiver includes a photo detector and preamplifier circuit, mounted within a 3-pin epoxy-encapsulated module that acts as an IR filter for improved PCM frequency. Three industry-standard pin configurations are available, with minimum irradiances of 0.1 mW/m² and 0.15 mW/m².
The devices are specified for operation from 2.5V to 5.5V with a transmission range of 45 meters. The modules feature a carrier frequency range 30-kHz to 56-kHz, offer a low 0.35-mA supply current, and comply with RoHS 2002/95/EC and WEEE 2002/96/EC.
Pricing: For U.S. delivery only is $1 each in small quantities.
Availability: Samples and production quantities are available now, with lead times of six weeks for large orders.
Datasheets: TSOP313, TSOP323, TSOP343, TSOP383 and TSOP393.
