4Mbps IrDA

Infrared Receiver

FEATURES

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 fre-

quency interference. The LT1328 plus five external com-

ponents is all that is required to make an IrDA compatible

receiver.

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.
