TDA1308; TDA1308A  
FEATURES  
GENERAL DESCRIPTION  
Wide temperature range  
No switch ON/OFF clicks  
Excellent power supply ripple rejection  
Low power consumption  
Short-circuit resistant  
High performance  
The TDA1308; TDA1308A is an integrated class AB stereo  
headphone driver contained in an SO8, DIP8 or a TSSOP8  
plastic package. The device is fabricated in a 1 mm CMOS  
process and has been primarily developed for portable  
digital audio applications.  
The difference between the TDA1308 and the TDA1308A  
is that the TDA1308A can be used at low supply voltages.  
– high signal-to-noise ratio  
– high slew rate  
– low distortion  
Large output voltage swing.

SOLDERING  
Introduction  
Typical reflow peak temperatures range from  
215 to 250 °C. The top-surface temperature of the  
packages should preferable be kept below 220 °C for  
thick/large packages, and below 235 °C for small/thin  
packages.  
This text gives a very brief insight to a complex technology.  
A more in-depth account of soldering ICs can be found in  
our “Data Handbook IC26; Integrated Circuit Packages”  
(document order number 9398 652 90011).  
WAVE SOLDERING  
There is no soldering method that is ideal for all IC  
packages. Wave soldering is often preferred when  
through-hole and surface mount components are mixed on  
one printed-circuit board. Wave soldering can still be used  
for certain surface mount ICs, but it is not suitable for fine  
pitch SMDs. In these situations reflow soldering is  
recommended.  
Conventional single wave soldering is not recommended  
for surface mount devices (SMDs) or printed-circuit boards  
with a high component density, as solder bridging and  
non-wetting can present major problems.  
To overcome these problems the double-wave soldering  
method was specifically developed.  
If wave soldering is used the following conditions must be  
observed for optimal results:  
Through-hole mount packages  
Use a double-wave soldering method comprising a  
turbulent wave with high upward pressure followed by a  
smooth laminar wave.  
SOLDERING BY DIPPING OR BY SOLDER WAVE  
The maximum permissible temperature of the solder is  
260 °C; solder at this temperature must not be in contact  
with the joints for more than 5 seconds. The total contact  
time of successive solder waves must not exceed  
5 seconds.  
For packages with leads on two sides and a pitch (e):  
– larger than or equal to 1.27 mm, the footprint  
longitudinal axis is preferred to be parallel to the  
transport direction of the printed-circuit board;  
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.  
– smaller than 1.27 mm, the footprint longitudinal axis  
must be parallel to the transport direction of the  
printed-circuit board.  
The footprint must incorporate solder thieves at the  
downstream end.  
For packages with leads on four sides, the footprint must  
be placed at a 45° angle to the transport direction of the  
printed-circuit board. The footprint must incorporate  
solder thieves downstream and at the side corners.  
MANUAL SOLDERING  
Apply the soldering iron (24 V or less) to the lead(s) of the  
package, either 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  
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.  
300 and 400 °C, contact may be up to 5 seconds.  
Surface mount packages  
Typical dwell time is 4 seconds at 250 °C.  
A mildly-activated flux will eliminate the need for removal  
of corrosive residues in most applications.  
REFLOW SOLDERING  
Reflow soldering requires solder paste (a suspension of  
fine solder particles, flux and binding agent) to be applied  
to the printed-circuit board by screen printing, stencilling or  
pressure-syringe dispensing before package placement.  
MANUAL SOLDERING  
Fix the component by first soldering two  
diagonally-opposite end leads. Use a low voltage (24 V or  
less) soldering iron 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.  
Several methods exist for reflowing; for example,  
convection or convection/infrared heating in a conveyor  
type oven. Throughput times (preheating, soldering and  
cooling) vary between 100 and 200 seconds depending  
on heating method.

Notes  
1. 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). For details, refer to the  
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.  
2. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.  
3. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink  
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).  
4. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.  
The package footprint must incorporate solder thieves downstream and at the side corners.  
5. Wave soldering is only suitable for LQFP, QFP and TQFP packages with a pitch (e) equal to or larger than 0.8 mm;  
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.  
6. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is  
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
