1 / 2 page NTE1578 Integrated Circuit FM Mixer/IF Amp Description: The NTE1578 is an FM front–end integrated circuit in a 16–Lead DIP type package designed for use in car radio and home stereo applications. This device has a built–in AGC driver circuit which im- proves interference characteristics. It thereby offers advantages such as improved interference char- acteristics without sacrificing usable sensitivity and the conventional DX–LOCAL change–over switch. Features: D Double–Balanced Type MIX (Improved Spurious Characteristic) D Keyed AGC/Keyed Classical AGC (Improved Intermodulation, Cross Modulation Characteristic) D Differential IF Amplification (Improved Limiting Characteristic) Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Maximum Supply Voltage (Pin12, Pin15), VCC1max 8.5V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
