• 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.

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 Ordering Information Type NO. SL2055 Marking SL2055 Package Cod.
