FEATURES
GENERAL DESCRIPTION
• Balanced limiting amplifier
The TDA1599 provides IF amplification, symmetrical
quadrature demodulation and level detection for quality
home and car FM radio receivers and is suitable for mono
and stereo reception. It may also be applied to common
front ends, stereo decoders and AM receiver circuits.
• Balanced coincidence demodulator
• Two open-collector stop pulse outputs for
microcomputer tuning control
• Simulated behaviour of a ratio detector (internal field
strength and detuning dependent voltage for dynamic
AF signal muting)
• Mono/stereo blend field strength indication control
voltage
• AFC output
• 3-state mode switch for FM-MUTE-ON, FM-MUTE-OFF
and FM-OFF
• Internal compensation of AF signal total harmonic
distortion (THD)
• Built-in hum and ripple rejection circuits.

TDA1599
Consequently, there is no need for the demodulator tuned
circuit to be adjusted for minimum distortion. Adjustment
criterion is a symmetrical stop pulse. The control voltage
for the mute attenuator (pin 16) is derived from the values
of the level detector and the detuning detector output
signals. The mute attenuator has a fast attack and a slow
decay determined by the capacitor on pin 16. The AF
signal is fed via the mute attenuator to the output (pin 4). A
weighted control voltage (pin 6) is obtained from the mute
attenuator control voltage via a buffer amplifier that
introduces an additional voltage shift and gain.
FUNCTIONAL DESCRIPTION
The limiter amplifier has five stages of IF amplification
using balanced differential limiter amplifiers with emitter
follower coupling.
Decoupling of the stages from the supply voltage line and
an internal high-ohmic DC feedback loop give a very stable
IF performance. The amplifier gain is virtually independent
of changes in temperature.
The FM demodulator is fully balanced and compromises
two cross-coupled differential amplifiers. The quadrature
detection of the FM signal is performed by direct feeding of
one differential amplifier from the limiter amplifier output,
and the other via an external 90 degrees phase shifting
network. The demodulator has a good stability and a small
zero-cross-over shift. The bandwidth on the demodulator
output is restricted by an internal low-pass filter to
approximately 1 MHz.
The level detector generates a voltage output signal
proportional to the amplitude of the input signal. The
unweighted level detector output signal is available in
FM-MUTE-ON condition (mode switch).
The open-collector tuning stop output voltages STOP-0
and STOP-1 (pins 15 and 14) are derived from the
detuning and the input signal level. The pins 14 and 15
may be tied together, if only one tuning-stop output is
required.
Non-linearities, which are introduced by demodulation, are
compensated by the THD compensation circuit. For this
reason, the demodulator resonance circuit (between pins
10 and 11) must have a loaded Q-factor of 19.

Several techniques exist for reflowing; for example,
SOLDERING
Introduction
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.
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 diagonally-
opposite 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.
