Overview
Ordering number : EN5661 Monolithic Linear IC LA4585M 3-V Preamplifier + Power Amplifier for Headphone Stereo Products Overview The LA4585M is a preamplifier plus power amplifier IC that supports auto-reverse and was developed for use in 3-V headphone stereo products.
Features • The LA4585M is designed for use in playback-only compact cassette players.
In addition to preamplifier and power amplifier functions, the LA4585M also provides low boost and automatic power output limiter (PVSS:Peak Volume Select System) functions.
• Provided in a mini-flat 36-pin quad package (0.
65 mm lead pitch) optimal for miniature end products.
• Two auto-reverse playback preamplifiers • Two headphone power amplifiers (16 Ω) • Low boost function (auto-loudness effect) • Output limiter function (PVSS) • Two radio input switches (pre-muting switches) • Power muting switch Package Dimensions unit: mm 3162B-QFP36 [LA4585M] Allowable power dissipation, Pd max – mW Ambient temperature, Ta – °C SANYO: QFP36 Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Allowable power dissipation Operating temperature Storage temperature Symbol VCC max Pd max Topr Tstg Conditions Ratings 4.
