Description of Electrical Characteristics

Described here are the terms of electric characteristics used in this datasheet. Items and symbols used are also shown.

Note that item name, symbol and their meaning may differ from those on other manufacturer’s document or general

documents.

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) 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.

Indicates the maximum voltage that can be applied between non-inverting and inverting terminals without damaging

the IC.

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.

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

the package (maximum junction temperature) and the thermal resistance of the package.

2. Electrical characteristics item

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.

Indicates the difference of input bias current between the non-inverting and inverting terminals.

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.

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

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)

Indicates the voltage range that the IC can output 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.

Indicates the input voltage range where IC operates normally.

The maximum current that can be output from the IC under specific output conditions. The output source current

indicates the current flowing out from the IC, and the output sink current indicates the current flowing into the IC.

(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)

(10) 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)

(11) Slew Rate (SR)

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

Indicates a frequency where the voltage gain of operational amplifier is 1.

(13) Gain Bandwidth (GBW)

Indicates to multiply by the frequency and the gain where the voltage gain decreases 6dB/octave.

(14) Phase Margin (

θ)

Indicates the margin of phase from 180 degree phase lag at unity gain frequency.

Indicates a noise voltage generated inside the operational amplifier reflected back to an ideal voltage source

connected in series with the input terminal.
