The LT
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.
Power requirements for the LT1328 are minimal—a single
5V supply and 2mA of quiescent current. Internal high-
pass 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.
