Ordering number: EN1272E Monolithic Linear IC LA1135, 1135M AM Tuner System for Car Radios and Home Stereos Overview The LA1135 is a high-performance AM electronic tuner IC that is greatly improved in cross modulation characteristics. It is especially suited for use in car radio and home stereo (antenna: loop) applications. Package Dimensions unit : mm 3021B-DIP20S [LA1135] Functions . MIX . OSC (with ALC) . IF amplifier . Detector . AGC (normal) . RF wide-band AGC . Auto search stop signal (signal meter output) . Local oscillation buffer output . Others unit : mm SANYO : DIP20S 3036B-MFP20 Features . Excellent cross modulation characteristics: Meets the . . . . . . . . . requirements for preventing not only adjacent-channel interference but also interference caused by all channels within broadcast band. Narrow-band signal meter output: Usable as auto search stop signal. Has linearity up to 80 dBµ. Local oscillation buffer output: Facilitates designing of electronic tuner system, frequency display, etc. OSC (with ALC): Improves tracking error because oscillation output is stabilized at a low level (380 mVrms) for varactor diode. MIX: Double-balanced differential MIX meeting the requirements for preventing spurious interference, IF interference. Good characteristics at high input: 130 dBµ input fm = 400 Hz 80% mod THD = 0.4% typ Low noise: Good S/N at medium input (56 dB typ) Usable sensitivity: (S/N = 20 dB input): 25 dBµ (2SK315 IDSS = 11mA) VCC variation compensation: Less variation in gain, distortion: 8 to 12 V Reduced pop noise: Capable of reducing pop noise at the time of VCC ON, mode select by adjusting AGC time constant.
