GENERAL DESCRIPTION
TEA5591A
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.

SOLDERING Introduction
TEA5591A
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. 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. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification 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. This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
