Overview
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.
Features
? Adjustment-free record bias current (automatic adjustment circuit adopted)
? Built-in record bias oscillator circuit power supply switch
? Record equalizer choke coil no longer required
? Playback amplifier input noise voltage: 1.0 μV rms
? Value of the ALC detector capacitor reduced (to 3.3 μF)
? Built-in high-voltage head switching circuit
? Supply voltage: supports both 9 and 12-V operation
? Built-in input switching circuit (for the line and tuner inputs)
Functions
? Equalizer amplifier
? Ripple filter
? Record/playback switching circuit
? Muting
? SP/LP/EP switching circuit
? Record amplifier
? ALC
? Tape head switching circuit
? Automatic record bias adjustment circuit
? Input switching circuit (line/tuner)
