FUNCTIONAL DESCRIPTION The TDA8561Q contains four identical amplifiers and can be used for Single-Ended (SE) or Bridge-Tied Load (BTL) applications. The gain of each amplifier is fixed at 20 dB (26 dB in BTL). Special features of the device are: The power dissipation in any short-circuit condition is very low. Mode select switch (pin 14) * Low standby current (<100 A) * Low switching current (low cost supply switch) MGA705 handbook, halfpage VO * Mute facility. 0 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 pins 1, 3, 15 and 17). This can be achieved by: V16 VP * Microcontroller control * External timing circuit (see Fig.11). 0 t Diagnostic output (pin 16) DYNAMIC DISTORTION DETECTOR (DDD) Fig.3 At the onset of clipping of one or more output stages, the dynamic distortion detector becomes active and pin 16 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 16 is independent of the number of channels that are clipping (see Figs 3 and 4). handbook, halfpage VO SHORT-CIRCUIT PROTECTION MGA706 0 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 16 is continuously LOW. V16 VP 0 When a short-circuit across the load of one or both channels occurs the output stages are switched off for approximately 20 ms. After that time it is checked during approximately 50 s to see whether the short-circuit is still present. Due to this duty cycle of 50 s/20 ms the average current consumption during this short-circuit condition is very low (approximately 40 mA). 1999 Jun 30 Distortion detector waveform; BTL application.

SOLDERING Introduction to soldering through-hole mount packages 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. This text gives a brief insight to wave, dip and manual soldering. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board. Manual soldering Apply the soldering iron (24 V or less) to the lead(s) of the package, either 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. Soldering by dipping or by solder wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joints for more than 5 seconds. Suitability of through-hole mount IC packages for dipping and wave soldering methods SOLDERING METHOD PACKAGE DIPPING DBS, DIP, HDIP, SDIP, SIL WAVE suitable(1) suitable Note 1. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
