TheTDA2320isamonolithicintegratedcircuitinDip
packageespeciallydesignedtoamplifytheIRsignal
in remotecontrolled TV or radio sets. It directly in­terfacesthedigital controlcircuitry.

The TDA2320 incorporates a two-stage amplifier
with excellentsensitivityandhighnoiseimmunity.It
can work with a single5Vsupplyvoltageand flash
orcarriertransmissionmodesasprovidedforexam­pleby theM709A/M710A/MOStransmitters.

The TDA2320isparticularlyintended to beused in
conjunctionwith the M104 and M206+ M3870 re­motecontrolreceivers.
