型號(hào)： NTE744

類(lèi)別： 集成電路

描述： 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: ? Low–noise, low–Rb, rf stage in cascode connection–eliminates Miller–Effect regeneration and allows controlled power rise by the choice of external components. ? Mixer–oscillator stage with internal feedback–eliminates need for tapped or multi–winding os cillator coils ? Cascode if amplifier with controlled output impedance and negligible Miller Effect–eliminates regeneration and selectivity skewing ? Frequency–counter AGC circuit–allows control of AGC response by selection of the coupling capacitor. ? Integral regulation with built–in surge protection ? Separately accessible amplifiers
