SL2055 Datasheet | Kodenshi AUK Group

Semiconductor 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 Ordering...
