The gain of each amplifier is fixed at 20 dB for SE and 26 dB for BTL. The device also contains an I2C-bus facility which operates in the read or write mode. In the write mode the device can be switched to either the sleep condition (low sleep current of 0.6 mA typ.), the MUTE condition or the ON condition. In the read mode an 8-bit status word is available. Data bits D0 to D3 contain status information of each of the 4 outputs. If the device is switched to the ON or MUTE condition and there is a short-circuit at one or more outputs, the power transistors will be outside their safe operating area consequently one or more bits of D0 to D3 will be HIGH. Bits D0 to D3 are LOW when in the normal safe operating area. Bit D4 is normally LOW if one or more channels reaches the clipping level D4 will go HIGH. Bit D5 is normally LOW, if the crystal temperature reaches 150 °C D5 will go HIGH. After a power-on reset bit 7 will go HIGH and a dip in the power supply will be noticed. Bit 7 will go LOW after the I2C-bus is read. When pin 9 is LOW the device will switch OFF and the supply current will be reduced to 0.1 mA (max.). junction handbook,virtual halfpage 6 8 10 12 4 K/W 0.8 K/W 0.1 K/W MLA009 Fig.3 Thermal equivalent resistance network.

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.
