Infrared receivers target low-speed data transmission
Rutronik is marketing two new miniaturised infrared receivers (IR) TSDP34138/56 and TSDP34338/56 from Vishay that are designed specifically for low-speed data transmission. They are optimised for low-complexity, low-cost signalling in metering, sensor, automation and gaming applications.
Specified for operation from 2.5V to 5.5V, with a low 0.35mA supply current at 3.3V, the new receivers each consist of a photodiode and preamplifier assembled on a lead frame. They provide low-speed data transmission up to 7.8kbps over a range of up to 35 meters with an emitter strength of 150mW/sr.
Offered in a compact 6.0 x 6.9 x 5.6mm epoxy package, that acts as IR band pass filter, the infrared receivers are optimised for use with inexpensive 940nm IR LEDs. They provide shielding against EMI and immunity against ambient light, and they are insensitive to supply voltage ripple and noise from CFL lamps. They meet the Vishay Green Standards and are RoHS-compliant as well as halogen-free.
Offering an alternative to radio frequency (RF) transmission, the IR components simplify designs, lower costs, and eliminate the need to obtain regulatory approvals. In addition, by requiring line-of-sight, IR enhances privacy and minimises interference with adjacent systems.
