TDA8559T
Low-voltage stereo headphone amplifier
Rev. 03 — 15 May 2006
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
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.

    Philips Semiconductors 8. Functional description The TDA8559T contains two amplifiers with differential inputs, a 0.5V high supply voltage stabilizer. Each amplifier consists of a voltage-to-current converter (V/I), an output amplifier and a common dynamic quiescent current controller. The gain of each amplifier is internally fixed at 26 dB (= 20 ).

  • Page 6: Dynamic Quiescent Controller

    These currents control the quiescent current. 8.5 Stabilizer The TDA8559T has a voltage supply range from 1.9 V to 30 V. This range is divided over two supply voltage pins. Pin 16 is 1.9 V to 18 V (breakdown voltage of the process); this pin is preferred for supply voltages less than 18 V.

    CWQCCN..L For more detailed information on the BGA packages refer to the (LF)BGA Application Note (AN01026); order a copy from your Philips Semiconductors sales office. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect).
