LA1185
FM Front-end for Radio-cassette Recorder, Home
Stereo Applications
Overview
The LA1185 is an FM receiver front-end IC for radio-cassette recorder, music center applications. Its mixer is of double-balanced type. The built-in oscillator and buffer amplifier improves the strong input characteristic.
Use
. FM front-end IC for radio-cassette recorders and music centers
Functions and Features
. RF amplifier, mixer, local oscillator
. Improvement in cross modulation characteristics due to the
. use of double-balanced mixer.
. Improvement in strong input characteristic.
. Minimum number of external parts required.
. Less spurious radiation from local oscillator. Operating voltage range : 1.5 to 8.0 V
