TDA2320
PREAMPLIFIER FOR INFRARED
REMOTE CONTROL SYSTEMS
DESCRIPTION
The TDA2320is a monolithic integrated circuit in Dip
package especially designedto amplify the IR signal
in remote controlled TV or radio sets. It directly in-
terfaces the digital control circuitry.
The TDA2320 incorporates a two-stage amplifier
with excellent sensitivity and high noise immunity. It
can work with a single 5V supply voltage and flash
or carrier transmission modes as provided for exam-
ple by the M709A/M710A/MOS transmitters.
The TDA2320 is particularly intended to be used in
conjunction with the M104 and M206 + M3870 re-
mote control receivers.
