AM/FM radio receiver circuit
GENERAL DESCRIPTION The TEA5594 is a 32-pin integrated radio circuit designed for use in all Electronic Tuned Radio (ETR) sets especially those sets which have to fulfil the immunity requirements of CENELEC. The AM circuit incorporates: * A double balanced mixer * A `one-pin' oscillator with amplitude control operating in the LW/MW frequency range * An IF amplifier and AM detector * An AGC circuit which controls the IF amplifier and mixer The FM circuit incorporates: * A front-end (fulfilling the "out of band" CENELEC requirements) * Two IF amplifiers (for distributed selectivity) * A quadrature demodulator with a ceramic filter PACKAGE OUTLINE 32-lead shrink DIL; plastic (SOT232); SOT232-1; 1996 September 9. The TEA5594 also contains:
TEA5594
* Oscillator output buffers for AM and FM * A combined AM/FM IF counter output buffer with counter "enable" function * A field strength level detector for AM and FM * A soft mute circuit at FM, adjustable * An extra IF amplifier to split up IF filtering Features * Low distortion on FM * AM/FM level/indicator circuit * A DC AM/FM switch facility * Supply voltages 2.7 to 15 V * A local distance switch facility (LOCAL-DX) at FM * All pins are ESD protected

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. 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. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values
TEA5594
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.
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.
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.
