HA12411 /HA1241& FM IF System HITACHI! HA12411* and HA12418* have been deveioped for the use of FM car radio. HA12411 is encapsulated in a | HA12411 DIP-16pin, and HA12418 in a SIP-16pin {Vertical Plastic Package). These ICs employ the same chips, and their functions and features are as follows. @ FUNCTIONS @ FM IF Amplifier @ Quandrature Detector (DP-16) Audio Post-Amptifier ee a @ Muting Circuit | HA12418 @ AFC, Center Meter Driver @ Muting Control Driver Analog Control Driver FEATURES @ Wide range of the operating supply Voltage @ Low distortion: T.H.D. = 0.06% typ. High Signal-to-Noise Ratio: S/N = 75dB typ. (SP-16) High Input Sensitivity: Vin (lim) = 31dBy typ. ee Te Capable of driving the signal meter under low input signal High stability against abnormal oscillation *Note) HA12411 and HA12418 have the pin-to-pin com- patibility with HA1137W.
