Note: Absolute maximum rating item indicates the condition which must not be exceeded. Application of voltage in excess of absolute maximum rating or use out absoluted maximum rated temperature environment may cause deterioration of characteristics. (*1) The voltage difference between inverting input and non-inverting input is the differential input voltage. Then input terminal voltage is set to more then VSS.

Technical Note
●Description of electrical characteristics Described here are the terms of electric characteristics used in this technical note. Items and symbols used are also shown. Note that item name and symbol and their meaning may differ from those on another manufacture’s document or general document. 1. Absolute maximum ratings Absolute maximum rating item indicates the condition which must not be exceeded. Application of voltage in excess of absolute maximum rating or use out of absolute maximum rated temperature environment may cause deterioration of dharacteristics. 1.1 Power supply voltage (VDD/VSS) Indicates the maximum voltage that can be applied between the positive power supply terminal and negative power supply terminalwithout deterioration or destruction of characteristics of internal circuit. 1.2 Differential input voltage (Vid) Indicates the maximum voltage that can be applied between non-inverting terminal and inverting terminal without deterioration and destruction of characteristics of IC. 1.3 Input common-mode voltage range (Vicm) Indicates the maximum voltage that can be applied to non-inverting terminal and inverting terminal without deterioration or destruction of characteristics. Input common-mode voltage range of the maximum ratings not assure normal operation of IC. When normalOperation of IC is desired, the input common-mode voltage of characteristics item must be followed. 1.4 Power dissipation (Pd) Indicates the power that can be consumed by specified mounted board at the ambient temperature 25℃(normal temperature). As for package product, Pd is determined by the temperature that can be permitted by IC chip in the package(maximum junction temperature) and thermal resistance of the package. 2. Electrical characteristics item 2.1 Input offset voltage (Vio) Indicates the voltage difference between non-inverting terminal and inverting terminal. It can be translated into the input voltage difference required for setting the output voltage at 0 [V]. 2.2 Input offset current (Iio) Indicates the difference of input bias current between non-inverting terminal and inverting terminal. 2.3 Input bias current (Ib) Indicates the current that flows into or out of the input terminal. It is defined by the average of input bias current at non-inverting terminal and input bias current at inverting terminal. 2.4 Circuit current (ICC) Indicates the IC current that flows under specified conditions and no-load steady status. 2.5 High level output voltage / Low level output voltage(VOH/VOL) Indicates the voltage range that can be output by the IC under specified load condition. It is typically divided into high-level output voltage and low-level output voltage. High-level output voltage indicates the upper limit of output voltage. Low-level output voltage indicates the lower limit. 2.6 Large signal voltage gain (AV) Indicates the amplifying rate (gain) of output voltage against the voltage difference between non-inverting terminal and inverting terminal.It is normally the amplifying rate (gain) with reference to DC voltage. Av = (Output voltage fluctuation) / (Input offset fluctuation) 2.7 Input common-mode voltage range (Vicm) Indicates the input voltage range where IC operates normally. 2.8 Common-mode rejection ratio (CMRR) Indicates the ratio of fluctuation of input offset voltage when in-phase input voltage is changed. It is normally the fluctuation of DC. CMRR ＝(Change of Input common-mode voltage)/(Input offset fluctuation) 2.9 Power supply rejection ratio (PSRR) Indicates the ratio of fluctuation of input offset voltage when supply voltage is changed. It is normally the fluctuation of DC. PSRR＝(Change of power supply voltage)/(Input offset fluctuation) 2.10 Channel separation(CS) Indicates the fluctuation of input offset voltage or that of output voltage with reference to the change of output voltage of driven channel.

Technical Note
2.11 Slew rate (SR) Indicates the time fluctuation ratio of voltage output when step input signal is applied. 2.12 Unity gain 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. ●Derating curve 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 ship 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 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 θj-a[℃/W]. The temperature of IC inside the package can be estimated by this thermal resistance. Fig.190 (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.190(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. Fig191(c)-(f) show a derating curve for an example of BU7261/41family,BU7262/42family.,7461/7441family,7462/7442family.
