September 1994 Fig.3 Pin configuration; TEA5711T. 5 Philips Semiconductors Product specification AM/FM stereo radio circuit TEA5711; TEA5711T FUNCTIONAL DESCRIPTION The AM circuit incorporates a double balanced mixer, a one pin low-voltage oscillator (up to 30 MHz) a field-strength indicator output and is designed for distributed selectivity. The AM input is designed to be connected to the top of a tuned circuit. AGC controls the IF amplification and for large signals it lowers the input impedance. The first AM selectivity can be an IFT as well as an IFT combined with a ceramic filter; the second one is an IFT. The FM circuit incorporates a tuned RF stage, a double balanced mixer, a one-pin oscillator, a field-strength indicator output and is designed for distributed IF ceramic filters. The FM quadrature detector uses a ceramic resonator.

Supply voltage behaviour The TEA5711 incorporates internal stabilized power supplies. The maximum supply voltage is 12 V, the minimum voltage can go down temporarily to 1.8 V without any loss in performance. Due to the capacitor at pin 19 (RIPPLE) the IC gives excellent performance, even when the actual supply voltage at pin 25 (VP) drops below the voltage at pin 19 (RIPPLE). Fig.5 Figures 4, 5 and 6 show that Vstab, which is dominant for the overall IC performance, remains unaffected, even if VP drops down to 1.8 V or less. In this typical example the static or average VP is equal to 2.5 V. Dips in Vstab appear only when the peak-to-peak value of the AC-component of VP > 2 V, i.e. when the dynamic value of VP drops down to 1.5 V for a short moment.

September 1994 24 2.65 2.35 Philips Semiconductors Product specification AM/FM stereo radio circuit TEA5711; TEA5711T SOLDERING BY SOLDER PASTE REFLOW Plastic dual in-line packages 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. 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 the 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.
