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.

2. Features

n Operating voltage from 1.9 V to 30 V

n Very low quiescent current

n Low distortion

n Few external components

n Differential inputs

n Usable as a mono ampliﬁer in Bridge-Tied Load (BTL) or stereo Single-Ended (SE)

n Single-ended mode without loudspeaker capacitor

n Mute and Standby mode

n Short-circuit proof to ground, to supply voltage (< 10 V) and across load

n No switch on or switch off clicks

n ESD protected on all pins

3. Applications

n Portable telephones

n MP3 players

n Portable audio

n Mains fed equipment
