Careful consideration must be given to the heat of the IC from the two standpoints of immediate damage and long-term reliability of operation. Pay attention to points such as the following. Since an maximum junction temperature (TjMAX.)or operating temperature range (Topr) is shown in the absolute maximum ratings of the IC, to reference the value, find it using the Pd-Ta characteristic (temperature derating curve). If an input signal is too great when there is insufficient radiation, TSD (thermal shutdown) may operate. TSD, which operates at a chip temperature of approximately +180℃, is canceled when this goes below approximately +100℃. Since TSD operates persistently with the purpose of preventing chip damage, be aware that long-term use in the vicinity that TSD affects decrease IC reliability.

(2) Although we are confident recommending the sample application circuit, carefully check their characteristics further when using them. When modifying externally attached component constants before use, determine them so that They have sufficient margins by taking into account variations in externally attached components and the Rohm IC,not only for static characteristics but also including transient characteristics. (3) Absolute maximum ratings This IC may be damaged if the absolute maximum ratings for the applied voltage, temperature range, or other parameters are exceeded. Therefore, avoid using a voltage or temperature that exceeds the absolute maximum ratings. If it is possible that absolute maximum ratings will be exceeded, use fuses or other physical safety measures and determine ways to avoid exceeding the IC's absolute maximum ratings. (4) GND terminal’s potential Try to set the minimum voltage for GND terminal’s potential, regardless of the operation mode. (5) Shorting between pins and mounting errors When mounting the IC chip on a board, be very careful to set the chip's orientation and position precisely.When the power is turned on, the IC may be damaged if it is not mounted correctly. The IC may also be damaged if a short occurs (due to a foreign object, etc.) between two pins, between a pin and the power supply, or between a pin and the GND. (6) Operation in strong magnetic fields Note with caution that operation faults may occur when this IC operates in a strong magnetic field. (7) Thermal design Ensure sufficient margins to the thermal design by taking in to account the allowable power dissipation during actual use modes, because this IC is power amp. When excessive signal inputs which the heat dissipation is insufficient condition, it is possible that thermal shutdown circuit is active. (8) Thermal shutdown circuit This product is provided with a built-in thermal shutdown circuit. When the thermal shutdown circuit operates, the output transistors are placed under open status. The thermal shutdown circuit is primarily intended to shut down the IC avoiding thermal runaway under abnormal conditions with a chip temperature exceeding Tjmax = +150℃, and is not intended to protect and secure an electrical appliance. (9) Load of the output terminal This IC corresponds to dynamic speaker load, and doesn't correspond to the load except for dynamic speakers. (10) The short protection of the output terminal The short-circuiting protection of this IC corresponds only to “VDD-short” (the short-circuiting with the power) of the output terminal and “GND-short” (the short-circuiting with GND) of the output terminal. It doesn't correspond to the short-circuiting among the output terminals. Also, when the short-circuiting condition of the output terminal is canceled, it detects the high impedance of the output terminal and it is equipped with the auto recover without power cycling(the cancellation) function in the short-circuiting protection. Be careful of the output terminal, because, there is a fear not to return automatically when the short-circuiting condition occurs in pull-up or the pull-down at equal to or less than about 1MΩ impedance, (11) Operating ranges The rated operating power supply voltage range (VDD=+2.5V ～ +5.5V) and the rated operating temperature range (Ta=-40℃～+85℃) are the range by which basic circuit functions is operated. Characteristics and rated output power are not guaranteed in all power supply voltage ranges or temperature ranges. (12) Electrical characteristics Electrical characteristics show the typical performance of device and depend on board layout, parts, power supply. The standard value is in mounting device and parts on surface of ROHM’s board directly. (13) Power decoupling capacitor Because the big peak current flows through the power line, the class-D amplifier has an influence on the Audio characteristic by the capacitance value or the arrangement part of the power decoupling capacitor. Arrange a power decoupling capacitor as close as possible to the VDD terminal of IC. www.rohm.com © 2010 ROHM Co., Ltd.
