Monolithic Linear IC
LA1862M
Single-chip Tuner System for Car Stereo
Overview
The LA1862M is a single-chip car stereo FM IF/NC/MPX
tuner IC which offers improved IF stability and S-meter
characteristics, compared with the LA1861M.
The LA1862M makes the design of high-performance FM
tuners at low cost easy.
