| Semiconductor SL5018/P LOW POWER NARROW BAND FM IF Description The SL5018/P is designed for use in FM dual conversion communication. It contains a complete narrow band FM demodulation system operable to less than 2.0V supply voltage. This low power narrow band FM IF system provides the second converter, second IF, demodulator. Filter Amp and squelch circuitry for communications and scanning receivers. Features * Operating voltage range : 2.0V ~ 8.0V * Low Current consumption ICC=4.0mA Typ. (VCC=4.0V) * Excellent input sensitivity (-3dB Limiting = 2.0 Vrms Typ.) * Low number of external parts required * Operating frequency up to 60MHz Ordering Information Type NO.
