IC is heated when it consumed power, and the temperature of IC chip becomes higher than ambient temperature. 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 indicatesthis 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.54(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.54(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 iis 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.55(c),(d) show a derating curve for an example of BA2904Y, BA2902Y.

Normal operation is not guaranteed within the 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 the 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 0 V. 2.2 Input offset voltage drift (△Vio/△T) Denotes the ratio of the input offset voltage fluctuation to the ambient temperature fluctuation. 2.3 Input offset current (Iio) Indicates the difference of input bias current between the non-inverting and inverting terminals. 2.4 Input offset current drift (△Iio/△T) Signifies the ratio of the input offset current fluctuation to the ambient temperature fluctuation. 2.5 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. 2.6 Circuit current (ICC) Indicates the current of the IC itself that flows under specified conditions and during no-load steady state. 2.7 High level output voltage/low level output voltage (VOH/VOL) Signifying the voltage range that can be output under specified load conditions, it is in general divided into high level output voltage and low level output voltage. High level output voltage indicates the upper limit of the output voltage, while low level output voltage the lower limit. 2.8 Large signal voltage gain (AV) The amplifying rate (gain) of the output voltage against the voltage difference between non-inverting and inverting terminals, it is (normally) the amplifying rate (gain) with respect to DC voltage. AV = (output voltage fluctuation) / (input offset fluctuation) 2.9 Input common-mode voltage range (Vicm) Indicates the input voltage range under which the IC operates normally. www.rohm.com © 2011 ROHM Co., Ltd. All rights reserved. 12/16 2011.08 - Rev.B BA2904YF-C,BA2904YFVM-C,BA2902YF-C,BA2902YFV-C Technical Note 2.10 Common-mode rejection ratio (CMRR) Signifies the ratio of fluctuation of the input offset voltage when the in-phase input voltage is changed (DC fluctuation). CMRR = (change in input common-mode voltage) / (input offset fluctuation) 2.11 Power supply rejection ratio (PSRR) Denotes the ratio of fluctuation of the input offset voltage when supply voltage is changed (DC fluctuation). SVR = (change in power supply voltage) / (input offset fluctuation) 2.12 Output source current/ output sink current (IOH/IOL) The maximum current that can be output under specific output conditions, it is divided into output source current and output sink current. The output source current indicates the current flowing out of the IC, and the output sink current the current flowing into the IC. 2.13 Channel separation (CS) Expresses the amount of fluctuation of the input offset voltage or output voltage with respect to the change in the output voltage of a driven channel. 2.14 Slew rate (SR) Indicates the time fluctuation ratio of the output voltage when an input step signal is supplied. 2.15 Gain bandwidth product (GBW) The product of the specified signal frequency and the gain of the op-amp at such frequency, it gives the approximate value of the frequency where the gain of the op-amp is 1 (maximum frequency, and unity gain frequency) www.rohm.com © 2011 ROHM Co., Ltd. All rights reserved. 13/16 2011.08 - Rev.B BA2904YF-C,BA2904YFVM-C,BA2902YF-C,BA2902YFV-C ●Notes for use 1) Unused circuits When there are unused circuits, it is recommended that they be connected as in Fig.56, setting the non-inverting input terminal to a potential within the in-phase input voltage range (Vicm). 2) Input voltage Applying VEE+36[V] to the input terminal is possible without causing deterioration of the electrical characteristics or destruction, irrespective of the supply voltage. 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. Technical Note VCC Please keep this 同相入力電圧 potencial in Vicm 範囲内の電位 VEE Fig. 56 Example of processing unused circuit 3) Power supply (single / dual) The op-amp operates when the voltage supplied is between VCC and VEE Therefore, the single supply op-mp 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 the 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 substances between the outputs, the output and the power supply, or the output and GND may result in IC destruction. 6) Operation in a strong electromagnetic field Operation in a strong electromagnetic field may cause malfunctions. 7) Radiation This IC is not designed to withstand radiation. 8) IC handing Applying mechanical stress to the IC by deflecting or bending the board may cause fluctuation of the electrical characteristics due to piezoelectric (piezo) effects. 9) IC operation The output stage of the IC is configured using Class C push-pull circuits. Therefore, when the load resistor is connected to the middle potential of VCC and VEE, crossover distortion occurs at the changeover between discharging and charging of the output current. Connecting a resistor between the output terminal and GND, and increasing the bias current for Class A operation will suppress crossover distortion. 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. 11) Output capacitor Discharge of the external output capacitor to VCC is possible via internal parasitic elements when VCC is shorted to VEE, causing damage to the internal circuitry due to thermal stress. Therefore, when using this IC in circuits where oscillation due to output capacitive load does not occur, such as in voltage comparators, use an output capacitor with a capacitance less than 0.1μF. 12) Oscillation by output capacitor Please pay attention to oscillation by output capacitor, designing application of negative feed back loop circuit with these ICs. www.rohm.com © 2011 ROHM Co., Ltd.
