GENERAL DESCRIPTION  
Single 6-bit Analog-to-Digital Converter (ADC) operation  
allowed up to 40 MSPS  
The TDA8706A is a 6-bit ADC with three analog  
multiplexed inputs. Each input has an analog clamp on  
code 0 for RGB video processing. Clamping level can also  
be adjusted externally up to code 20. It can also be used  
as a single 6-bit ADC.  
External control of clamping level  
Internal reference voltage (external reference allowed)  
Power dissipation only 36 mW (typical)  
Operating temperature of 40 to +85 °C  
Operating between 2.7 and 3.6 V  
Sine wave clock allowed.

Notes  
1. In addition to a good layout of the digital and analog ground, it is recommended that the rise and fall times of the clock  
must not be less than 1 ns. A sine wave with specified amplitude is also allowed.  
2. Effective bits are derived from a Fast Fourier Transform (FFT) processing taking 2K acquisition points per equivalent  
fundamental period. The calculation takes into account all harmonics and noise up to half of the clock frequency  
(NYQUIST frequency). Conversion to signal-to-noise ratio: S/N = EB × 6.02 + 1.76 dB.  
3. Output data acquisition: the output data is available after the maximum delay time td.

The analog and digital supplies should be separated and decoupled.  
VDDO should be well decoupled with its capacitor in order to be as close as possible to its pin.  
VRB must not be connected to VCLPR, VCLPB or VCLPG pins.  
For applications where the black level is clamped to code 0, VCLPR, VCLPB and VCLPG must be left open-circuit with their respective decoupling  
capacitors. In that event, they may also be connected together in order to use only one single decoupling capacitor.  
(1) VRB is decoupled to VSSA. An external regulator can also be connected to VRB  
.
(2) VCLPR, VCLPB and VCLPG are decoupled to VSSA. External voltages can also be forced on VCLPR, VCLPB and VCLPG  
.
(3) VDDO and VDDO can be shorted together but the decoupling capacitors should remain as close as possible to its pin.

SOLDERING  
If wave soldering is used the following conditions must be  
observed for optimal results:  
Introduction to soldering surface mount packages  
Use a double-wave soldering method comprising a  
turbulent wave with high upward pressure followed by a  
smooth laminar wave.  
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).  
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;  
There is no soldering method that is ideal for all surface  
mount IC packages. 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.  
– smaller than 1.27 mm, the footprint longitudinal axis  
must be parallel to the transport direction of the  
printed-circuit board.  
Reflow soldering  
The footprint must incorporate solder thieves at the  
downstream end.  
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.  
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.  
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.  
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.  
Typical reflow peak temperatures range from  
215 to 250 °C. The top-surface temperature of the  
packages should preferably be kept:  
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.  
below 220 °C for all the BGA packages and packages  
with a thickness 2.5mm and packages with a  
thickness <2.5 mm and a volume 350 mm3 so called  
thick/large packages  
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.  
below 235 °C for packages with a thickness <2.5 mm  
and a volume <350 mm3 so called small/thin packages.  
Wave soldering  
When using a dedicated tool, all other leads can be  
soldered in one operation within 2 to 5 seconds between  
270 and 320 °C.  
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.

Notes  
1. 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.  
2. 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”.  
3. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder  
cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,  
the solder might be deposited on the heatsink surface.  
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 suitable for LQFP, TQFP and QFP packages with a pitch (e) 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 suitable for SSOP, TSSOP, VSO and VSSOP 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.
