GENERAL DESCRIPTION
The TDA8559 is a stereo amplifier that operates over a
wide supply voltage range from 1.9 to 30 V and consumes
a very low quiescent current. This makes it suitable for
battery fed applications (2
×
1.5 V cells). Because of an
internal voltage buffer, this device can be used with or
without a capacitor connected in series with the load. It can
be applied as a headphone amplifier, but also as a mono
amplifier with a small speaker (25
), or as a line driver in
mains applications.
