FEATURES
GENERAL DESCRIPTION
• Two independent amplifiers with open-loop gain of
90 dB (typical)
The TDA1522 is a playback amplifier for car radio/cassette
players.
• Internal DC feedback via 140 kΩ resistor from output to
feedback point
• AC characteristics that can be determined externally by
an RC network
• Electronic on/off switching with transient suppression for
switch on
• Head input at DC ground that eliminates the input
coupling capacitor
• Minimum external component requirement
• Stability down to a gain of 30 dB
• Low input noise
• Low distortion
• DC input current <2 µA
• Wide supply voltage range.

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.
