LA1136NM - AM Tuners

This page provides the datasheet information for the LA1136NM, a member of the LA1136N AM Tuners family.

Features

  • . 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 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 (350.
