1998 apr 07 5 philips semiconductors preliminary speci?cation 70 w high ef?ciency power ampli?er with diagnostic facility tda1562q functional description the tda1562q contains a mono class-h btl output power amplifier. at low output power, up to 18 w, the device operates as a normal btl amplifier. when a larger output voltage swing is required, the internal supply voltage is lifted by means of the external electrolytic capacitors. due to this momentarily higher supply voltage the obtainable output power is 70 w. in normal use, when the output is driven with music-like signals, the high output power is only needed during a small percentage of time. under the assumption that a music signal has a normal (gaussian) amplitude distribution, the reduction in dissipation is about 50% when compared to a class-b output amplifier with the same output power. the heatsink should be designed for use with music signals. if the case temperature exceeds 120 c, the device will switch back from class-h to class-b operation. the high power supply voltage is then disabled and the output power is limited to 20 w. when the supply voltage drops below the minimum operating level, the amplifier will be muted immediately. mode select input (pin mode) this pin has 3 modes: 1. low, standby: the complete circuit is switched off, the supply current is very low 2. mid, mute: the circuit is switched on, but the input signal is suppressed 3. high, on: normal operation, the input signal is amplified by 26 db. when the circuit is switched from mute to on or vice versa the actual switching takes place at a zero crossing of the input signal. the circuit contains a quick start option, i.e. when it is switched directly from standby to on, the amplifier is fully operational within 50 ms (important for applications like car telephony and car navigation). status i/o input (pin stat) i nput this input has 3 possibilities: 1. low, fast mute: the circuit remains switched on, but the input signal is suppressed 2. mid, class-b: the circuit operates as class-b amplifier, the high power supply voltage is disabled, independent of the case temperature 3. high, class-h: the circuit operates as class-h amplifier, the high power supply voltage is enabled, independent of the case temperature. when the circuit is switched from fast mute to class-b/h or vice versa the switching is immediately carried out. when the circuit is switched from class-b to class-h or vice versa the actual switching takes place at a zero crossing of the input signal. o utput this output has 3 possibilities: 1. low, mute: acknowledge of muted amplifier 2. mid, class-b: the circuit operates as class-b amplifier, the high power supply voltage is disabled, caused by the case temperature t c > 120 c 3. high, class-h: the circuit operates as class-h amplifier, the high power supply voltage is enabled, because the case temperature t c < 120 c. when the circuit is switched from class-b to class-h or vice versa the actual switching takes place at a zero crossing of the input signal. the status i/o pins of maximum 8 devices may be tied together for synchronizing purposes.

1998 apr 07 16 philips semiconductors preliminary speci?cation 70 w high ef?ciency power ampli?er with diagnostic facility tda1562q 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. 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. 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 (t stg 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. 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. definitions life support applications these products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify philips for any damages resulting from such improper use or sale. data sheet status objective speci?cation this data sheet contains target or goal speci?cations for product development. preliminary speci?cation this data sheet contains preliminary data; supplementary data may be published later. product speci?cation this data sheet contains ?nal product speci?cations. limiting values limiting values given are in accordance with the absolute maximum rating system (iec 134). stress above one or more of the limiting values may cause permanent damage to the device. these are stress ratings only and operation of the device at these or at any other conditions above those given in the characteristics sections of the speci?cation is not implied. exposure to limiting values for extended periods may affect device reliability. application information where application information is given, it is advisory and does not form part of the speci?cation.
