TDA2320

PREAMPLIFIER FOR INFRARED

REMOTE CONTROL SYSTEMS

DESCRIPTION

DIP8

(Plastic Package)

The TDA2320is amonolithicintegratedcircuit in Dip

packageespeciallydesignedto amplifytheIRsignal

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 carriertransmission modesasprovidedfor exam-

ple by the M709A/M710A/MOStransmitters.
