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.
• Single-ended mode without loudspeaker capacitor
• Mute and standby mode
• Short-circuit proof to ground, to supply voltage (<10 V)
and across load
• No switch on or switch off clicks
• ESD protected on all pins.

FUNCTIONAL DESCRIPTION
V/I converters
The TDA8559 contains two amplifiers with differential
inputs, a 0.5VP output buffer and a 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 ×). The 0.5VP output can be
used as a replacement for the single-ended capacitors.
The two amplifiers can also be used as a mono amplifier in
a BTL configuration thereby resulting in more output
power.
The V/I converters have a transconductance of 400 µS.
The inputs are completely symmetrical and the two
amplifiers can be used in opposite phase. The mute mode
causes the V/I converters to block the input signal.
The input mode pin selects two applications in which the
V/I converters can be used.
The first application (input mode pin floating) is used with
a supply voltage below 6 V. The input DC level is at ground
level (the unused input pin connected to ground) and no
input coupling capacitors are necessary. The maximum
converter output current is sufficient to obtain an output
swing of 3 V (peak).
With three mode select pins, the device can be switched
into the following modes:
1. Standby mode (IP < 10 µA)
In the second application with a supply voltage greater
than 6 V (input mode pin HIGH), the input mode pin is
connected to VP. In this configuration (input DC
level = 0.5VP + 0.6 V) the input source must be coupled
with a capacitor and the two unused input pins must be
connected via a capacitor to ground, to improve noise
performance. This application has a higher quiescent
current, because the maximum output current of the V/I
converter is higher to obtain an output voltage swing of
9 V (peak).
2. Mute mode
3. Operation mode, with two input selections (the input
source is directly connected or connected via coupling
capacitors at the input).
The ripple rejection in the stereo application with a
single-ended capacitor can be improved by connecting a
capacitor between the 0.5VP capacitor pin and ground.
The device is fully protected against short-circuiting of the
output pins to ground, to the low supply voltage pin and
across the load.

TDA8559
Output amplifiers
Stabilizer
The output amplifiers have a transresistance of 50 kΩ, a
bandwidth of approximately 750 kHz and a maximum
output current of 100 mA. The mid-tap output voltage
equals the voltage applied at the non-inverting pin of the
output amplifier. This pin is connected to the output of the
0.5VP buffer. This reduces the distortion when the load is
connected between an output amplifier and the buffer
(because feedback is applied over the load).
The TDA8559 has a voltage supply range from
1.9 to 30 V. This range is divided over two supply voltage
pins. Pin 16 is 1.9 to 18 V (breakdown voltage of the
process); this pin is preferred for supply voltages less than
18 V. Pin 15 is used for applications where VP is
approximately 6 to 30 V. The stabilizer output is internally
connected to the supply voltage pin 16. In the range from
6 to 18 V, the voltage drop to pin 16 is 1 V. In the range
from 18 to 30 V the stabilizer output voltage (to pin 16) is
approximately 17 V.
Buffer
The buffer delivers 0.5VP to the output with a maximum
output (sink and source) current of 200 mA (peak).
Input logic
The MUTE pin (pin 7) selects the mute mode of the V/I
converters. LOW (TTL/CMOS) level is mute. A voltage
between 0.5 V (low level) and 1.5 V (high level) causes a
soft mute to operate (no plops). When pin 7 is floating or
greater than 1.5 V it is in the operating condition.
Dynamic quiescent controller
The Dynamic Quiescent Current controller (DQC) gives
the advantage of low quiescent current and low distortion.
When there are high frequencies in the output signal, the
DQC will increase the quiescent current of the two output
amplifiers and the buffer. This will reduce the cross-over
distortion that normally occurs at high frequencies and low
quiescent current. The DQC gives output currents that are
linear with the amplitude and the frequency of the output
signals. These currents control the quiescent current.
The input mode pin must be connected to VP when the
supply voltage is greater than 6 V. The input mode logic
raises the tail current of the V/I converters and enables the
two buffers to bias the inputs of the V/I converters.
Reference
This circuit supplies all currents needed in this device. With
the standby mode pin 1 (TTL/CMOS), it is possible to
switch to the standby mode and reduce the total quiescent
current to below 10 µA.

APPLICATION INFORMATION
Test conditions
General
Tamb = 25 °C; unless otherwise specified: VP = 3 V,
f = 1 kHz, RL = 32 Ω, Gain = 26 dB, low input mode,
band-pass filter: 22 Hz to 30 kHz. The total harmonic
distortion as a function of frequency was measured with
low-pass filter of 80 kHz. The quiescent current has been
measured without any load impedance.
For applications with a maximum supply voltage of 6 V
(input mode LOW) the input pins need a DC path to ground
(see Figs 3 and 4). For applications with supply voltages in
the range from 6 to 18 V (input mode HIGH) the input DC
level is 0.5VP + 0.6 V. In this situation the input
configurations illustrated in Figs 5 and 6 have to be used.
In applications with coupling capacitors towards the load,
an electrolytic capacitor has to be connected to pin 4
(SVRR).
The capacitor Cb is recommended for stability
improvement. The value may vary between
10 and 100 nF. This capacitor should be placed close to
the IC between pin 12 and pin 13.
• The graphs for the single-ended application have been
measured with the application illustrated in Fig.9; input
configuration for input mode low (Fig.4) and input
configuration for input mode high (Fig.6).
Heatsink design
• The graphs for the BTL application ‘input mode low’
have been measured with the application circuit
illustrated in Fig.11 and the input configuration
illustrated in Fig.4.
The standard application is stereo headphone
single-ended with a 32 Ω load impedance to buffer
(see Fig.9). The headphone amplifier can deliver a peak
output current of 150 mA into the load.
• The graphs for the line-driver application have been
measured with the application circuit illustrated in Fig.13
and the input configuration illustrated in Fig.6; input
mode high.

at pin 8:
For the SO16 envelope Rth j-amb = 105 K/W; the maximum
sinewave power dissipation for Tamb = 25 °C is:
1. Input mode low: pin 8 floating:
The DC level of the input pins has to be between 0 V
and (VP − 1.8 V). A DC path to ground is needed.
The maximum output voltage is approximately
2.1 V (RMS). Input configurations illustrated in
Figs 3 and 4 should be used.

2. Input mode high: pin 8 is connected to VP:
This mode is intended for supply voltages >6 V. It can
deliver a maximum output voltage of approximately
6 V (RMS) at THD = 0.5%. The DC voltage level of the
input pins is (0.5VP + 0.6 V). Coupling capacitors are
necessary. Input configurations illustrated in
Figs 5 and 6 should be used.

Low-voltage stereo headphone amplifier
TDA8559
Application 1: SE with loudspeaker capacitor
(see Fig.8)
Application 6: Line driver application 6 V < VP < 18 V
(see Fig.13)
The value of capacitor Cr influences the behaviour of the
Supply Voltage Ripple Rejection (SVRR) at low
frequencies; increasing the value of Cr increases the
performance of the SVRR.
The TDA8559T delivers a virtual rail-to-rail output voltage.
Because the input mode has to be high, the input
configurations illustrated in Figs 5 and 6 should be used.
This application can also be used for headphone
application, however, due to the limited output current and
the limited output power at the headphone, series resistors
have to be used between the output pins and the load.
Application 2: SE to buffer (without loudspeaker
capacitor) (see Fig.9)
The value of capacitor Cr influences the behaviour of the
SVRR at low frequencies; increasing the value of Cr
increases the performance of the SVRR.
This is the basic headphone application. The advantage of
this application with respect to application 1, is that it
needs only one external component (Cb) in the event of
stability problems.
Application 7: Line driver application 6V < VP < 30 V
(see Fig.14)
Application 3: Improved SE to buffer (without
loudspeaker capacitor) (see Fig.10)
With the supply voltage connected to pin 15 it is possible
to use the head amplifier above the maximum of 18 V to
pin 16. The internal supply voltage will be reduced to a
maximum of approximately 17 V.
This application is an improved configuration of
application 2. The distinction between the two is
connecting the loads in opposite phase. This lowers the
average current through the SE buffer.
It should be noted that a headphone cannot be used
because the load requires floating terminals.
This will be convenient in applications where the supply
voltage is higher than 18 V, however an output voltage
swing that reaches the higher supply voltage is not
required. the input configurations illustrated in
Figs 5 and 6 should be used. This application can also be
used for headphone applications. However, due to the
limited output current, series resistors have to be used
between the output pins and the load.
Application 4: Bridge tied load mono amplifier
(see Fig.11)
This configuration delivers four times the output power of
the SE application with the same supply and load
conditions. The capacitor Cr is not required.
Application 5: Line driver application 1.9 V < VP < 6 V
(see Fig.12)
The TDA8559 delivers a virtual rail-to-rail output voltage
and is also usable in a low voltage environment, as a line
driver. In this application the input needs a DC path to
ground, input configurations illustrated in Figs 3 and 4
should be used. The value of capacitor Cr influences the
behaviour of the SVRR at low frequencies; increasing the
value of Cr increases the performance of the SVRR.

Low-voltage stereo headphone amplifier
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
WAVE SOLDERING
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
Wave soldering techniques can be used for all SO
packages if the following conditions are observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
DIP
SOLDERING BY DIPPING OR BY WAVE
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
• The package footprint must incorporate solder thieves at
the downstream end.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (Tstg max). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.
REPAIRING SOLDERED JOINTS
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
REPAIRING SOLDERED JOINTS
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
SO
REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO
packages.
Reflow soldering requires solder paste (a suspension of
