Low-voltage stereo headphone amplifier
Product specification
TDA8559
FEATURES
• Operating voltage from 1.9 to 30 V
• Very low quiescent current
• Low distortion
• Few external components
• Differential inputs
• Usable as a mono amplifier in Bridge-Tied Load (BTL) or
stereo Single-Ended (SE)
• Single-ended mode without loudspeaker capacitor
• Mute and standby mode
• Short-circuit proof to ground, to supply voltage (<10 V)
and across load

• ESD protected on all pins.
APPLICATIONS
• Portable telephones
• Walk-mans
• Portable audio
• Mains fed equipment.
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 Ω), or as a line driver in
mains applications.
