PREAMPLIFIER FOR REMOTE CONTROL USE

Description

• The SL 2055 is bipolar IC for receiving preamplifier of infrared remote control system. It

consists of a head amplifier, a limiter, a band pass filter, a signal waveform detector, and a

waveform rectifier, etc.

Features

• Built-in filter enable to vary center frequency by an external resistance

(fo=30KHz to 80KHz, 38KHz typ.)

• Possible to direct connection to a photo diode.

• Open collector output(directly connectable to TTL and CMOS)

• Internal pull-up resistance and power filter resistance(low-capacitance)

• Less chances of malfunction associated with a high frequency lighting floure internal trap

circuit
