Monolithic Linear IC
LA4582CM
Pre + Power Amplifier for 3-V Headphone Stereo Systems
Overview
The LA4582CM is a preamplifier plus power amplifier IC that support auto-reverse, and was developed for 3-V headphone stereo systems.
Features
* The LA4582CM was developed for cassette playback systems, and in addition to preamplifier and power amplifier functions, it also provides low boost and automatic power limitation (PVSS: Peak Volume Select System) functions.
* Provided in a 36-pin miniature flat package (0.65 mm lead pitch) that is optimal for set miniaturization. * Capable of driving 8- speakers * Two-channel playback auto-reverse preamplifier * Two-channel headphone power amplifier * Low-frequency boost function (auto-loudness effect) * Output suppression function (PVSS) * Two-channel radio input switch (pre-mute switch) * Power mute switch
