SL2055
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
