LA1135M

`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 dB.
`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 dB input f_m = 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 dB (2SK315 I_DSS = 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 V_CC ON, mode select by adjusting AGC time constant.

The LA1135M is a high-performance AM electronic tuner IC that is greatly improved in cross modulation characteristics. LA1135M is especially suited for use in car radio and home stereo (antenna: loop) applications.
