IC FOR HEADPHONE STEREOS MONOLITHIC IC D665
GENERAL DESCRIPTION
D665 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.
F E AT U R E S
z Broad operating voltage range of 2.0 to
5.0V (amp system operates to 1.8V)
z Few external components required
Outline drawing
1. Internal equalizer resistance
2. Direct coupling of preamps, electronic VR, power amp
3. No need for output coupling capacitor
z Well-balanced electronic VR, A-curve attenuation characteristic obtained with
B-curve VR
z Internal motor control circuit , with noise from motor driving unit suppressed
z Provided with pin to turn off preamps
z Package: SOP28
