The gain of each amplifier is fixed at 40 dB. Special features of the device are as follows.

GND2 8 power ground 2 OUT 2B 9 output 2B Since this pin has a very low input current (<40 µA), a low cost supply switch can be applied. VP2 10 supply voltage 2 MODE 11 mode switch input VDIAG 12 diagnostic output To avoid switch-on plops, it is advised to keep the amplifier in the mute mode during ≥100 ms (charging of the input capacitors at pin 1 and pin 13). IN 2 13 input 2 This can be achieved by: • Microprocessor control • External timing circuit (see Fig.7). Diagnostic output (pin 12) DYNAMIC DISTORTION DETECTOR (DDD) IN 1 1 GND(S) 2 V P1 3 OUT 1A 4 GND1 5 OUT 1B 6 OUT 2A 7 GND2 8 OUT 2B 9 At the onset of clipping of one or more output stages, the dynamic distortion detector becomes active and pin 12 goes low. This information can be used to drive a sound processor or DC volume control to attenuate the input signal and thus limit the distortion. The output level of pin 12 is independent of the number of channels that are clipping (see Fig.3).

SHORT-CIRCUIT PROTECTION When a short-circuit occurs at one or more outputs to ground or to the supply voltage, the output stages are switched off until the short-circuit is removed and the device is switched on again, with a delay of approximately 20 ms, after removal of the short-circuit. During this short-circuit condition, pin 12 is continuously low. The power dissipation in any short-circuit condition is very low. TEMPERATURE DETECTION When the virtual junction temperature Tvj reaches 150 °C, pin 12 will become continuously low. When a short-circuit across the load of one or both channels occurs the output stages are switched off during approximately 20 ms. After that time it is checked during approximately 50 µs to see whether the short-circuit is still present. Due to this duty cycle of 50 µs/20 ms the average current consumption during this short-circuit condition is very low (approximately 40 mA). OPEN COLLECTOR OUTPUT Pin 12 is an open collector output, which allows pin 12 of more devices being tied together. handbook, full pagewidthcurrent MGA722 in output stage V12 t short-circuit over the load 20 ms VP 50 µs Fig.4 Short-circuit waveform. 1996 Jan 08 5 t Philips Semiconductors Product specification 2 × 40 W/2 Ω stereo BTL car radio power amplifier with diagnostic facility TDA8560Q LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).

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.
