Description of Electrical Characteristics

Described below are descriptions of the relevant electrical terms used in this datasheet. Items and symbols used are also

shown. Note that item name and symbol and their meaning may differ from those on another manufacturer’s document or

general document.

1. Absolute Maximum Ratings

Absolute maximum rating items indicate 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 characteristics.

1.1 Power Supply Voltage (VCC-VEE)

Indicates the maximum voltage that can be applied between the positive power supply terminal and negative power

supply terminal without 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 and inverting terminals without damaging

the IC.

1.3 Input Common-mode Voltage Range (VICM)

Indicates the maximum voltage that can be applied to the non-inverting and inverting terminals 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.

1.4 Power Dissipation (PD)

Indicates the power that can be consumed by the IC when mounted on a specific board at the ambient temperature 25℃

(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 Item

2.1 Input Offset Voltage (VIO)

Indicates the voltage difference between non-inverting terminal and inverting terminals. 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 the non-inverting and inverting terminals.

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 currents at

the non-inverting and inverting terminals.

2.4 Input Common-mode Voltage Range (VICM)

Indicates the input voltage range where IC normally operates.

2.5 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) / (Differential Input voltage)

2.6 Circuit Current (ICC)

Indicates the current that flows within the IC under specified no-load conditions.

2.7 Output Saturation Voltage (VOM)

Signifies the voltage range that can be output under specific output conditions.

2.8 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)

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 in the output voltage of the driven channel with reference to the change of output voltage of

the channel which is not driven.

2.11 Slew Rate (SR)

Indicates the ratio of the change in output voltage with time when a step input signal is applied.
