Philips TDA8559T - Manual

1. General description
The TDA8559T is a stereo amplifier that operates over a wide supply voltage range from
1.9 V 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
Ω
), or as a line driver in mains applications.
