Vishay Strengthens Its Optoelectronics Portfolio [Health & Beauty Close - Up]
(Health & Beauty Close - Up Via Acquire Media NewsEdge) Vishay Intertechnology said that it has broadened its optoelectronics portfolio with the release of two new miniaturized infrared (IR) receivers designed specifically for low-speed data transmission.
The TSDP34138/56 and TSDP34338/56 are optimized for low- complexity, low-cost signaling in metering, sensor, automation, and gaming applications, the Company noted in its release.
Specified for operation from 2.5 V to 5.5 V, with a low 0.35 mA supply current at 3.3 V, Vishay said that its Semiconductors receivers released recently each consist of a photodiode and preamplifier assembled on a lead frame. The devices' epoxy package - - measuring 6.0 mm by 6.9 mm by 5.6 mm -- acts as an IR band pass filter for use with inexpensive 940 nm IR LEDs.
Using amplitude-shift keyed (ASK) on-off modulated 38.4 kHz or 57.6 kHz signals from an emitter with a 250 mW/sr irradiance, the TSDP34138/56 and TSDP34338/56 achieve continuous data transmission up to 7.8 kbps over a range up to 35 meters. In addition, the receivers provide shielding against EMI, immunity against ambient light, and are insensitive to supply voltage ripple and noise from CFL lamps.
Data transmission is a central element in a wide range of electronics. As an alternative to radio frequency (RF) transmission, Vishay noted that the use of IR components such as the TSDP34138/56 and TSDP34338/56 simplifies designs, lowers costs, and eliminates the need to obtain regulatory approvals. In addition, by requiring line-of-sight, IR enhances privacy and minimizes interference with adjacent systems.
