FEATURES
GENERAL DESCRIPTION
• 8-bit resolution
The TDA8716 is an 8-bit high-speed Analog-to-Digital
Converter (ADC) designed for HDTV and professional
applications. The device converts the analog input signal
into 8-bit binary coded digital words at a sampling rate of
120 MHz. All digital outputs are ECL compatible.
• Sampling rate up to 120 MHz
• ECL (10 K family) compatible digital inputs and outputs
• Overflow/Underflow output
• Low power dissipation
• Low input capacitance (13 pF typ.).
APPLICATIONS
• High speed analog-to-digital convertion
• Video signal digitizing
• Radar pulse analysis
• Transient signal analysis
• High energy physics research
• Medical systems
• Industrial instrumentation.
QUICK REFERENCE DATA
Measured over full voltage and temperature ranges, unless otherwise specified.

Notes
1. Voltage offset BOTTOM (VOB) is the difference between the analog input which produces data outputs equal to 00
and the reference voltage BOTTOM (VRB), at Tamb = 25 °C. Voltage offset TOP (VOT) is the difference between
reference voltage TOP (VRT) and the analog input which produces data outputs equal to FF, at Tamb = 25 °C.
2. The analog input is not internally biased. It should be externally biased between VRB and VRT levels.
3. The TDA8716 can only withstand one or two 10K or 100K ECL loads in order to work-out timings at the maximum
sampling frequency. It is therefore recommended to minimize the printed-circuit board load by implementing the load
device as close as possible to the TDA8716.
4. Full-scale sinewave; fi = 4.43 MHz; fCLK, fCLK = 100 MHz.
5. Effective bits are obtained via a Fast Fourier Transformer (FFT) treatment taking 4 K acquisition points per period.
The calculation takes into account all harmonics and noise up to half of the clock frequency (NYQUIST frequency).
Conversion to SNR: SNR = EB (dB) × 6.02 + 1.76.

Typical value for resistors = 2.2 kΩ.
Lower resistor values can be used down to 500 Ω to obtain higher sampling frequencies in the 150 MSPS range (limited by td and tHD timings). In this
configuration a DC shift of the ECL output levels VOL and VOH will occur.
VRB, VRT and VM are decoupled to AGND.
Analog, digital and output supplies should be separated and decoupled.
The external voltage regulator must be constructed in such a way that a good supply voltage ripple rejection is achieved with respect to the LSB value.

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
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.
