Monolithic Linear IC

LA1136N, 1136NM, 1137N, 1137NM

AM Tuners for Car Radios and Home Stereos

Overview

Features

The LA1136N/NM 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.

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 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 dBµ 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 dBµ

(when using 2SK715 )

Circuit preventing incorrect seek operation

predecessors)

Improved capability for driving external RF AGC transistors:

I_Bmax = 200 µA

Measures to prevent incorrect seek operation

IF count buffer on chip; controlled by microcontroller

Time constant switching circuit on chip for RF and IF

AGC

IF AGC clear circuit on chip

Measures that prevent stopping one station too soon
