RF/IF circuit for AM/FM radio
TEA5570
GENERAL DESCRIPTION
The TEA5570 is a monolithic integrated radio circuit for use in portable receivers and clock radios. The IC is also
applicable to mains-fed AM and AM/FM receivers and car radio-receivers. Apart from the AM/FM switch function the IC
incorporates for AM a double balanced mixer, 'one-pin' oscillator, i.f. amplifier with a.g.c. and detector, and a level
detector for tuning indication. The FM circuitry comprises i.f. stages with a symmetrical limiter for a ratio detector. A level
detector for mono/stereo switch information and/or indication complete the FM part.
Features
• Simple d.c. switching for AM to FM by only one d.c. contact to ground (no switch contacts in the i.f. channel, a.f. or
level detector outputs)
• AM and FM gain control
• Low current consumption (I = 6 mA)
tot
• Low voltage operation (V = 2,7 to 9 V)
P
• Ability to handle large AM signals; good i.f. suppression
• Applicable for inductive, capacitive and diode tuning
• Double smoothing of a.g.c. line
• Short-wave range up to 30 MHz
• Lumped or distributed i.f. selectivity with coil and/or ceramic filters
• AM and a.g.c. output voltage control
• Distribution of PCB wiring provides good frequency stability
• Economic design for 'AM only' receivers.

Product specification
RF/IF circuit for AM/FM radio
TEA5570
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
SOLDERING
Introduction
specified maximum storage temperature (T
). If the
stg max
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
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.
