SL2055 - PREAMPLIFIER FOR REMOTE CONTROL USE

General 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.

Key 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 Ordering Information Type NO. SL2055 Marking SL2055 Package Cod.
