LA1845NV
Monolithic Linear IC
Single-Chip Home Stereo IC
The LA1845NV is designed for use in mini systems and is a single-chip tuner IC that provides electronic tuning
functions using SD/IF-count technique. It incorporates a pilot canceler and an adjustment-free MUX VCO circuit,
thus allows additional parts to be reduced.
