The TEA5594 also contains:
GENERAL DESCRIPTION
• Oscillator output buffers for AM and FM
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.
• 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
The AM circuit incorporates:
• A double balanced mixer
• An extra IF amplifier to split up IF filtering
• A ‘one-pin’ oscillator with amplitude control operating in
Features
the LW/MW frequency range
• An IF amplifier and AM detector
• Low distortion on FM
• An AGC circuit which controls the IF amplifier and mixer
• 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
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

Product specification
AM/FM radio receiver circuit
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.
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.
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 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.

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.
