PREAMPLIFIER FOR INFRARED

REMOTE CONTROL SYSTEMS

DE SC RI P TI O N

The TDA2320is a monolithic integratedcircuit 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.
