LT1328 4Mbps Ir DA Infrared Receiver Features s s s s s s DESCRIPTION The LT ®1328 is a photodiode receiver that supports Ir DA® 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 ponents is all that is required to make an Ir DA patible receiver. Power requirements for the LT1328 are minimal- a single 5V supply and 2m A 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. The LT1328’s ease of use and flexibility make it an ideal solution for numerous other photodiode receiver applications. The LT1328 is available in the SO-8 as well as the tiny MSOP for size-critical applications. , LTC and LT are registered trademarks of Linear Technology Corporation.
