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.

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 θj-a[℃/W]. The temperature of IC inside the package can be estimated by this thermal resistance. Fig.195 (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.195(b) indicates power that can be consumed by IC with reference to ambient temperature. 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. Fig196(c) ~ (h) show a derating curve for an example of low voltage full swing [W] CMOS Op-Amp.
