Notes to the characteristics
1. The circuit is DC adjusted at VP = 6 V to 18 V and AC operating at VP = 8.5 V to 18 V.
2. At 18 V < VP < 30 V the DC output voltage ≤ VP/2.
3. Conditions:a) V11 = 0 Vb) short-circuit to GNDc) switch V11 to MUTE or ON condition (rise time ≥ 10 µs).
4. Frequency response externally fixed.
5. Ripple rejection measured at the output with a source impedance of 0 Ω (maximum ripple amplitude of 2 V).
6. Frequency f = 100 Hz.
7. Frequency between 1 kHz and 10 kHz.
8. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
9. Noise output voltage independent of RS (VI = 0 V).

TDA1552Q
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed thespecified maximum storage temperature (Tstg max). If theprinted-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep thetemperature within the permissible limit.

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred whenthrough-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering isnot always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In thesesituations reflow soldering is often used.

Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to thelead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of thesoldering iron bit is less than 300 °C it may remain incontact 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 is260 °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.
