IF amplifier/demodulator for FM radio receivers  
TDA1597  
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 connected to 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 gives a very  
stable IF performance. The amplifier gain is virtually  
independent of changes in temperature.  
The FM demodulator is fully balanced and contains two  
cross-coupled differential amplifiers.  
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  
the FM-MUTE-ON condition (mode switch).  
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  
of the demodulator output is restricted by an internal  
low-pass filter to approximately 1 MHz. Non-linearities,  
which are introduced by demodulation, are compensated  
for 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.  
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. Pins 14 and 15 may be  
tied together if only one tuning-stop output is required.

SOLDERING  
BY SOLDER PASTE REFLOW  
Reflow soldering requires the solder paste (a suspension  
of fine solder particles, flux and binding agent) to be  
applied to the substrate by screen printing, stencilling or  
pressure-syringe dispensing before device placement.  
Plastic dual in-line packages  
BY DIP OR WAVE  
The maximum permissible temperature of the solder is  
260 °C; this temperature must not be in contact with the  
joint for more than 5 s. The total contact time of successive  
solder waves must not exceed 5 s.  
Several techniques exist for reflowing; for example,  
thermal conduction by heated belt, infrared, and  
vapour-phase reflow. Dwell times vary between 50 and  
300 s according to method. Typical reflow temperatures  
range from 215 to 250 °C.  
The device may be mounted up to the seating plane, but  
the temperature of the plastic body must not exceed the  
specified storage maximum. 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.  
Preheating is necessary to dry the paste and evaporate  
the binding agent. Preheating duration: 45 min at 45 °C.  
REPAIRING SOLDERED JOINTS (BY HAND-HELD SOLDERING  
IRON OR PULSE-HEATED SOLDER TOOL)  
REPAIRING SOLDERED JOINTS  
Fix the component by first soldering two, diagonally  
opposite, end pins. Apply the heating tool to the flat part of  
the pin only. Contact time must be limited to 10 s at up to  
300 °C. When using proper tools, all other pins can be  
soldered in one operation within 2 to 5 s at between 270  
and 320 °C. (Pulse-heated soldering is not recommended  
for SO packages.)  
Apply a low voltage soldering iron below the seating plane  
(or not more than 2 mm above it). If its temperature is  
below 300 °C, it must not be in contact for more than 10 s;  
if between 300 and 400 °C, for not more than 5 s.  
Plastic small outline packages  
BY WAVE  
For pulse-heated solder tool (resistance) soldering of VSO  
packages, solder is applied to the substrate by dipping or  
by an extra thick tin/lead plating before package  
placement.  
During placement and before soldering, the component  
must be fixed with a droplet of adhesive. After curing the  
adhesive, the component can be soldered. The adhesive  
can be applied by screen printing, pin transfer or syringe  
dispensing.  
Maximum permissible solder temperature is 260 °C, and  
maximum duration of package immersion in solder bath is  
10 s, if allowed to cool to less than 150 °C within 6 s.  
Typical dwell time is 4 s at 250 °C.  
A modified wave soldering technique is recommended  
using two solder waves (dual-wave), in which a turbulent  
wave with high upward pressure is followed by a smooth  
laminar wave. Using a mildly-activated flux eliminates the  
need for removal of corrosive residues in most  
applications.
