●Notes for use
Technical Note
1) Unused circuits When there are unused circuits it is recommended that they are connected as in Fig.98, setting the non-inverting input terminal to a potential within input common-mode voltage range (Vicm). 2) Input terminal voltage Applying GND + 36V 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. 3) Power supply (single / dual) The op-amp operates when the specified voltage supplied is between VCC and VEE. Therefore, the single supply op-amp can be used as dual supply op-amp as well.
Please keep this potential in Vicm
VCC
+ VEE
Fig.98 Unused circuit example
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) 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 fluctuations in the electrical characteristics due to piezoelectric (piezo) effects. 9) 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. 10) 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.

Technical Note
●Derating curves Power dissipation(total loss) indicates the power that can be consumed by IC at Ta=25℃(normal temperature). 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 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.99 (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: ・・・・・ (Ⅰ) θja = (Tj-Ta) / Pd [℃/W] Derating curve in Fig.99 (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.100(c) ~ (f) shows a derating curve for an example of BA3472, BA3474, BA3472R, BA3474R. LSI の 消 費 電 力 [ W]

It is typically divided into high-level output voltage and low-level output voltage. 2.6 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) 2.7 Input common-mode voltage range (Vicm) Indicates the input voltage range under which the IC operates normally. 2.8 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) 2.9 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) 2.10 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. 2.11 Slew rate (SR) Indicates the time fluctuation ratio of the output voltage when an input step signal is supplied. 2.12 Maximum frequency (ft) Indicates a frequency where the voltage gain of Op-Amp is 1. 2.13 Total harmonic distortion + Noise (THD+N) Indicates the fluctuation of input offset voltage or that of output voltage with reference to the change of output voltage of driven channel. 2.14 Input referred noise voltage (Vn) Indicates a noise voltage generated inside the operational amplifier equivalent by ideal voltage source connected in series with input terminal.
