LA7285

Ordering number:EN4091 Monolithic Linear IC LA7285, 7285M VCR Audio Signal Recording and Playback Processor Overview The LA7285 and LA7285M include on chip all functions required for the record and playback of VCR audio signals. In addition, the inclusion of a switching circuit for switching between tuner and line input in addition to the circuits provided by earlier ICs makes the LA7285 truly optimal for audio VCR products. Package Dimensions unit:mm 3067-DIP24S [LA7285] Funtions Equalizer amplifier Line amplifier Recording/playback switch Recording amplifier Mute SP, LP, EP switch Ripple filter ALC Tape head switch Line/tuner input switch SANYO:DIP24S unit:mm 3112-MFP24S [LA7285M] Features Built-in input switching circuit (for the line and tuner inputs). Smaller package leaves large space for other components. Equalizer input/output capacitors not required. Low gain variation eliminates the need for external ajustment. Supply voltage : 9V and 12V operation.
