NTE744

NTE744 Integrated Circuit RF/IF Amp Description: The NTE744 is a monolithic silicon integrated circuit that provides an rf amplifier, if amplifier, mixer, oscillator, AGC detector, and voltage regulator on a single chip. It is intended for use in super–heterodyne AM radio receiver applications particularly in automobiles. The NTE744 is supplied in a 14–lead dual–in–line plastic package and operates over the temperature range of –55° to 125°C. Features: D Low–noise, low–Rb, rf stage in cascode connection–eliminates Miller–Effect regeneration and allows controlled power rise by the choice of external components. D Mixer–oscillator stage with internal feedback–eliminates need for tapped or multi–winding oscillator coils D Cascode if amplifier with controlled output impedance and negligible Miller Effect–eliminates regeneration and selectivity skewing D Frequency–counter AGC circuit–allows control of AGC response by selection of the coupling capacitor. D Integral regulation with built–in surge protection D Separately accessible amplifiers Absolute Maximum Ratings: DC Supply Voltage (Pin3), V+ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9V DC Supply Voltage (IF Output, Pin6) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40V DC Supply Voltage (RF Output, Pin13) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20V ...
