IR Receivers Rated For Automotive Temperature Range

Designed for use in automobile entertainment systems, the TSOP48xxxxAM series miniaturized IR receiver modules are said to be the industry's first such devices approved for a storage temperature range of −40°C to +90°C. The modules integrate a photo detector, preamplifier, and an AGC in a single epoxy package measuring 6 mm x 6.95 mm x 5.6 mm. The package also doubles as an IR filter. Optimized for multimedia applications, the devices deliver a demodulated output signal that can be decoded directly by a microprocessor. Operating voltage ranges from 4.5V to 5.5V. The modules are available in seven standard carrier frequencies ranging from 30 kHz to 56 kHz with a burst length of 10 cycles/burst. In 100,000-piece quantities, pricing starts at $80/100.
