NTE1624
Integrated Circuit
AM/FM Radio Circuit
w
/Power Amp
Features:
D
Suitable for Use in AM/FM Portable Radios or Main鈥揻ed AM/FM Clock Radios.
D
Incorporates AM RF Amp, AM Local Oscillator, AM Mixer, AM/FM IF Amp, AM/FM Detector,
AM AGC Circuit, FM AFC Circuit and B Class鈥揂udio Power Amplifier.
D
Using the NTE1624, Plus the Discrete Input Stage (for FM: RF Amp and Converter), It is Pos-
sible to Construct a Complete AM/FM Radios Receivers.
D
Wide Operating Voltage Range: 3V to Approx 13V, Depending on the Internal Regulator Toler-
ance.
D
As the Internal Shunt Voltage Regulator Circuit is Connected to the Supply Voltage Terminal, it
Permits a Constant Current Mode (Approximately 42mA) of Operation which is Desirable for
Line鈥揙perated Equipments.
D
AM to FM Switching is Accomplished by Switching Only DC Circuitry.
