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. LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134). SYMBOL PARAMETER CONDITIONS MIN. MAX.

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. 1997 Feb 27 21 Philips Semiconductors Product specification IF amplifier/demodulator for FM radio receivers TDA1597 DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development. Preliminary specification This data sheet contains preliminary data; supplementary data may be published later. Product specification This data sheet contains final product specifications. Limiting values Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale. 1997 Feb 27 22 Philips Semiconductors Product specification IF amplifier/demodulator for FM radio receivers NOTES 1997 Feb 27 23 TDA1597 Philips Semiconductors - a worldwide company Argentina: see South America Australia: 34 Waterloo Road, NORTH RYDE, NSW 2113, Tel. +61 2 9805 4455, Fax. +61 2 9805 4466 Austria: Computerstr. 6, A-1101 WIEN, P.O.
