The temperature that can be accepted by IC chip depends on circuit configuration, manufacturing process, and consumable power is limited. Power dissipation is determined by the temperature allowed in IC chip (maximum junction temperature) and thermal resistance of package (heat dissipation capability). The maximum junction temperature is typically equal to the maximum value in the storage temperature range. Heat generated by consumed power of IC radiates from the mold resin or lead frame of the package. The parameter which indicates this heat dissipation capability(hardness of heat release)is called thermal resistance, represented by the symbol θja[℃/W].The temperature of IC inside the package can be estimated by this thermal resistance. Fig.51(a) shows the model of thermal resistance of the package. Thermal resistance θja, ambient temperature Ta, junction temperature Tj, and power dissipation Pd can be calculated by the equation below θja = (Tj-Ta) / Pd [℃/W] ・・・・・ (Ⅰ) Derating curve in Fig.51(b) indicates power that can be consumed by IC with reference to ambient temperature. Power that can be consumed by IC begins to attenuate at certain ambient temperature. This gradient is determined by thermal resistance θja. Thermal resistance θja depends on chip size, power consumption, package, ambient temperature, package condition, wind velocity, etc even when the same of package is used. Thermal reduction curve indicates a reference value measured at a specified condition. Fig.52(c),(d) show a derating curve for an example of BA2903Y, BA2901Y.

Please note that item names, symbols, and their meanings may differ from those on another manufacturer’s documents. 1.Absolute maximum ratings The absolute maximum ratings are values that should never be exceeded, since doing so may result in deterioration of electrical characteristics or damage to the part itself as well as peripheral components. 1.1 Power supply voltage (VCC/VEE) Expresses the maximum voltage that can be supplied between the positive and negative power supply terminals without causing deterioration of the electrical characteristics or destruction of the internal circuitry. 1.2 Differential input voltage (Vid) Indicates the maximum voltage that can be supplied between the non-inverting and inverting terminals without damaging the IC. 1.3 Input common-mode voltage range (Vicm) Signifies the maximum voltage that can be supplied to non-inverting and inverting terminals without causing deterioration of the electrical characteristics or damage to the IC itself. Normal operation is not guaranteed within the input common-mode voltage range of the maximum ratings – use within the input common-mode voltage range of the electric characteristics instead. 1.4 Operating and storage temperature ranges (Topr, Tstg) The operating temperature range indicates the temperature range within which the IC can operate. The higher the ambient temperature, the lower the power consumption of the IC. The storage temperature range denotes the range of temperatures the IC can be stored under without causing excessive deterioration of the electrical characteristics. 1.5 Power dissipation (Pd) Indicates the power that can be consumed by a particular mounted board at ambient temperature (25℃). For packaged products, Pd is determined by maximum junction temperature and the thermal resistance. 2.Electrical characteristics 2.1 Input offset voltage (Vio) Signifies the voltage difference between the non-inverting and inverting terminals. It can be thought of as the input voltage difference required for setting the output voltage to 0V. 2.2 Input offset current (Iio) Indicates the difference of the input bias current between the non-inverting and inverting terminals. 2.3 Input bias current (Ib) Denotes the current that flows into or out of the input terminal, it is defined by the average of the input bias current at the non-inverting terminal and the input bias current at the inverting terminal. 2.4 Input common-mode voltage range (Vicm) Indicates the input voltage range under which the IC operates normally. 2.5 Large signal voltage gain (AV) The amplifying rate (gain) of the output voltage against the voltage difference between the non-inverting and inverting terminals, it is (normally) the amplifying rate (gain) with respect to DC voltage. AV = (output voltage fluctuation) / (input offset fluctuation) 2.6 Circuit current (ICC) Indicates the current of the IC itself that flows under specific conditions and during no-load steady state. 2.7 Output sink current (IOL) Denotes the maximum current that can be output under specific output conditions. 2.8 Output saturation voltage low level output voltage (VOL) Signifies the voltage range that can be output under specific output conditions. 2.9 Output leakage current, High level output current (Ileak) Indicates the current that flows into the IC under specific input and output conditions. 2.10 Response time (Tre) The interval between the application of input and output conditions. www.rohm.com © 2011 ROHM Co., Ltd.

However, this does not ensure normal circuit operation. Please note that the circuit operates normally only when the input voltage is within the common mode input voltage range of the electric characteristics. VCC + Please keep this potential in Vicm (Vicm＞VEE) OPEN － VEE Fig. 53 Disable circuit example 3) Power supply (signal / dual) The op-amp operates when the specified voltage supplied is between VCC and VEE. Therefore, the signal supply op-amp can be used as a dual supply op-amp as well. 4) Power dissipation Pd Using the unit in excess of the rated power dissipation may cause deterioration in electrical characteristics due to a rise in chip temperature, including reduced current capability. Therefore, please take into consideration the power dissipation (Pd) under actual operating conditions and apply a sufficient margin in thermal design. Refer to the thermal derating curves for more information. 5) Short-circuit between pins and erroneous mounting Incorrect mounting may damage the IC. In addition, the presence of foreign particles between the outputs, the output and the power supply, or the output and GND may result in IC destruction. 6) Terminal short-circuits When the output and VCC terminals are shorted, excessive output current may flow, resulting in undue heat generation and, subsequently, destruction. 7) Operation in a strong electromagnetic field Operation in a strong electromagnetic field may cause malfunctions. 8) Radiation This IC is not designed to withstand radiation. 9) IC handing Applying mechanical stress to the IC by deflecting or bending the board may cause fluctuations in the electrical characteristics due to piezoelectric (piezo) effects. 10) Board inspection Connecting a capacitor to a pin with low impedance may stress the IC. Therefore, discharging the capacitor after every process is recommended. In addition, when attaching and detaching the jig during the inspection phase, ensure that the power is turned off before inspection and removal. Furthermore, please take measures against ESD in the assembly process as well as during transportation and storage www.rohm.com © 2011 ROHM Co., Ltd.
