Vishay Releases Five New Series of High-Sensitivity AGC3 IR Receivers Optimized for Noisy Environments and Short Burst Codes
Devices Offer a 2.5-V to 5.5-V Supply Voltage Range and Low Power Consumption of 0.35 mA in Three Industry-Standard PIN Configurations
MALVERN, Pa. — Jan. 30, 2008 — In a move to minimize the impact of fluorescent lamps (CFLs) and other disturbance signals on IR remote control systems, Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of five new series of high-sensitivity IR receivers. As AGC3 devices, the receivers are optimized for noisy environments and short burst codes.
One of the leading sources of environmental optical noise is compact fluorescent lamps, which emit noise signals that resemble IR remote control signals, severely impacting the performance of IR systems.
To help minimize this impact, Vishay has released the new TSOP313.., TSOP323.., TSOP343.., TSOP383.., and TSOP393.. series of ultra-noise-resistant AGC3 IR remote control receivers. The devices provide extreme robustness against all disturbance signals and better suppress spurious pulses from energy-saving fluorescent lamps.
With a higher resistance to ESD, improved shielding against EMI, and improved 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 new devices are specified for operation from 2.5 V to 5.5 V 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.
