LA1137NM

`Excellent cross modulation characteristic: 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 100 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 (350 mVrms: LA1137N) for varactor diode.
`MIX: Double-balanced differential MIX meeting the requirements for preventing spurious interference, IF interference.
`Good characteristic at high input: 130 dB input fm = 400 Hz 80%mod THD = 0.5% typ.
`High S/N: Good S/N at medium input (55 dB typ).
`Usable sensitivity: (S/N = 20 dB input): 25 dB (when using 2SK715 )
`VCC variation compensation: Less variation in gain, distortion: 8 to 12 V

The LA1137NM and LA1137N/NM are high-performance AM electronic tuner ICs offering sophisticated functions. They are especially suited for use in car radio and home stereo (antenna: loop) applications.
