IC for Headphone Stereos LAG665
Outline
This IC was developed for use in headphone stereos, and incorporates dual preamp, power amp, electronic
VR and motor control circuits. It can be used in a simple circuit configuration which requires very few external
components.
Features
1. Broad operating voltage range of 2.0 to 5.0 V (amp system operates to 1.8 V)
2. Few external components required
1. Internal equalizer resistance
2. Direct coupling of preamps, electronic VR, power amp
3. No need for output coupling capacitor
3. Well-balanced electronic VR, A-curve attenuation characteristic obtained with B-curve VR
4. Internal motor control circuit, with noise from motor driving unit suppressed
5. Provided with pin to turn off preamps
