Description

The LA7289 includes on chip all functions required for the record and playback of VCR audio signals and achieves complete adjustment-free operation by the adoption of an automatic record bias current adjustment circuit. 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 LA7289 truly optimal for audio VCR products.
