INTEGRATED CIRCUITS DATA SHEET TDA7010T FM radio circuit Product specification File under Integrated Circuits, IC01 September 1983 Philips Semiconductors Product specification FM radio circuit TDA7010T GENERAL DESCRIPTION The TDA7010T is a monolithic integrated circuit for mono FM portable radios, where a minimum on peripheral components is important (small dimensions and low costs). The IC has an FLL (Frequency-Locked-Loop) system with an intermediate frequency of 70 kHz. The i.f. selectivity is obtained by active RC filters. The only function which needs alignment is the resonant circuit for the oscillator, thus selecting the reception frequency. Spurious reception is avoided by means of a mute circuit, which also eliminates too noisy input signals. Special precautions are taken to meet the radiation requirements. The TDA7010T includes the following functions: • R.F. input stage • Mixer • Local oscillator • I.F. amplifier/limiter • Phase demodulator • Mute detector • Mute switch QUICK REFERENCE DATA 2,7 to 10 V Supply voltage range (pin 4) VP Supply current at VP = 4,5 V IP typ.

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. 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. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 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). 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. 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. 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. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 °C. Wave soldering 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. • The longitudinal axis of the package footprint must be parallel to the solder flow. • The package footprint must incorporate solder thieves at the downstream end.
