INTEGRATED CIRCUITS DATA SHEET TEA5591A AM/FM radio receiver circuit Product specification File under Integrated Circuits, IC01 February 1990 Philips Semiconductors Product specification AM/FM radio receiver circuit TEA5591A GENERAL DESCRIPTION The TEA5591A is a 24-pin integrated radio circuit, derived from the TEA5591 and is designed for use in AM/FM portable radios and clock radios. The TEA5591A differs from the TEA5591 in that it has: • Separate IF input pins for AM and FM • A split-up AM-IF stage (for distributed selectivity) • An LED driver indicator The main advantage of the TEA5591A is its ability to operate over a wide range of supply voltages (1.8 to 15 V) without any loss of performance. The AM circuit incorporates: • A double balance mixer • A ‘one-pin’ oscillator with amplitude control operating in the 0.6 to 30 MHz frequency range • A split-up IF amplifier • A detector • An AGC circuit which controls the IF amplifier and mixer. The FM circuit incorporates: • An RF input amplifier • A double balanced mixer • A ‘one-pin’ oscillator • Two IF amplifiers (for distributed selectivity) • A quadrature demodulator for a ceramic filter • Internal AFC Features • LED AM/FM indicator • A DC AM/FM switch facility • Three separate stabilizers to enable operation over a wide range of supply voltages (1.8 to 15 V) • All pins (except pin 10) are ESD protected PACKAGE OUTLINE 24-lead shrink DIL; plastic (SOT234); SOT234-1; 1996 September 9.

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. 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). Soldering by dipping or by wave 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 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. Repairing soldered joints 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.
