DESCRIPTION
The LT ®1328 is a photodiode receiver that supports IrDA® data rates up to 4Mbps as well as other modulation methods such as Sharp ASK and TV remote control. The LT1328 MSOP contains all the necessary circuitry to convert current pulses from an external photodiode to a digital TTL output while rejecting unwanted lower frequency interference. The LT1328 plus five external components is all that is required to make an IrDA compatible receiver. Power requirements for the LT1328 are minimal—a single 5V supply and 2mA of quiescent current. Internal highpass filtering attenuates interfering signals such as sunlight, incandescent and fluorescent lamps and is selectable at Pin 7 for low or high data rates.
