12 W car radio power amplifier TDA1020

The TDA1020 is a monolithic integrated 12 W audio amplifier in a 9-lead single in-line (SIL) plastic package. The device
is primarily developed as a car radio amplifier. At a supply voltage of VP= 14,4 V, an output power of 7 W can be delivered
into a 4 Ω load and 12 W into 2 Ω.

To avoid interferences and car ignition signals coming from the supply lines into the IC, frequency limiting is used beyond
the audio spectrum in the preamplifier and the power amplifier.

The maximum supply voltage of 18 V makes the IC also suitable for mains-fed radio receivers, tape recorders or record
players. However, if the supply voltage is increased above 18 V (< 45 V), the device will not be damaged (load dump
protected). Also a short-circuiting of the output to ground (a.c.) will not destroy the device. Thermal protection is built-in.
As a special feature, the circuit has a low stand-by current possibility.

The TDA1020 is pin-to-pin compatible with the TDA1010.

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”

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 (T
be necessary immediately after soldering to keep the temperature within the permissible limit.

(order code 9398 652 90011).

). If the printed-circuit board has been pre-heated, forced cooling may

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.
