The gain of each amplifier is fixed at 26 dB. Special features of this device are: Mute/stand-by switch • low stand-by current (< 100 µA) • low mute/stand-by switching current (low cost supply switch) • mute facility. Loudspeaker protection When a short-circuit to ground is made, which forces a DC voltage across the loudspeaker of ≥ 1 V, a built-in protection circuit becomes active and limits the DC voltage across the loudspeaker to ≤ 1 V. The delay time of the protection circuit can be controlled by an external capacitor connected to pin 12.

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.
