Items and symbols used are also shown. Note that item names, symbols, and their meanings may differ from those of another manufacturer’s document or general document. 1. Absolute Maximum Ratings Absolute maximum rating items indicate the conditions which must not be exceeded. Application of voltage in excess of the absolute maximum rating or use out of absolute maximum rated temperature environment may cause deterioration of electrical characteristics. (1) Supply Voltage (VCC/VEE) Indicates the maximum voltage that can be applied between the VCC pin and VEE pin without deterioration of characteristics of internal circuit. (2) Differential Input Voltage (VID) Indicates the maximum voltage that can be applied between the non-inverting and inverting pins without damaging the IC. (3) Input Common-mode Voltage Range (VICM) Indicates the maximum voltage that can be applied to the non-inverting and inverting pins without deterioration or destruction of electrical characteristics. Input common-mode voltage range of the maximum ratings does not assure normal operation of IC. For normal operation, use the IC within the input common-mode voltage range characteristics. (4) Power Dissipation (PD) Indicates the power that can be consumed by the IC when mounted on a specific board at the ambient temperature 25°C (normal temperature). As for package product, PD is determined by the temperature that can be permitted by the IC in the package (maximum junction temperature) and the thermal resistance of the package. 2. Electrical Characteristics (1) Input Offset Voltage (VIO) Indicates the voltage difference between non-inverting pin and inverting pin. It can be translated to the input voltage difference required for setting the output voltage to 0V. (2) Input Offset Voltage Drift (∆VIO/∆T) Denotes the ratio of the input offset voltage fluctuation to the ambient temperature fluctuation. (3) Input Offset Current (IIO) Indicates the difference of input bias current between the non-inverting and inverting pins. (4) Input Bias Current (IB) Indicates the current that flows into or out of the input pin. It is defined by the average of input bias currents at the non-inverting and inverting pins. (5) Supply Current (ICC) Indicates the current that flows within the IC under specified no-load conditions. (6) Maximum Output Voltage (High) / Maximum Output Voltage (Low) (VOH/VOL) Indicates the voltage range of the output under specified load condition. It is typically divided into maximum output voltage high and low. Maximum output voltage high indicates the upper limit of output voltage. Maximum output voltage low indicates the lower limit. (7) Large Signal Voltage Gain (AV) Indicates the amplification rate (gain) of output voltage against the voltage difference between non-inverting pin and inverting pin. It is normally the amplification rate (gain) with reference to DC voltage. Av = (Output Voltage) / (Differential Input Voltage) (8) Input Common-mode Voltage Range (VICM) Indicates the input voltage range at which IC normally operates. (9) Common-mode Rejection Ratio (CMRR) Indicates the ratio of fluctuation of input offset voltage when the input common-mode voltage is changed. It is normally the fluctuation of DC. CMRR = (Change of Input Common-mode Voltage)/(Input Offset Fluctuation) |
