Datasheet
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.
1.1 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.
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 the non-inverting terminal and inverting terminal without
deterioration or destruction of characteristics. Input common-mode voltage range of the maximum ratings not assures
normal operation of IC. When normal Operation 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 the IC when mounted on a specific board at ambient temperature 25°C (normal
temperature). As for the packaged 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 terminal. It can be translated into the
input voltage difference required for setting the output voltage to 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 currents at
non-inverting and inverting terminals.
2.4 Input Common-mode Voltage Range (Vicm)
Indicates the input voltage range where IC operates normally.
2.5 Maximum Output Voltage (VOM)
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.
2.6 Large Signal Voltage Gain (Av)
Indicates the amplification rate (gain) of the output voltage against the voltage difference between the non-inverting
and inverting terminals. It is normally the amplification rate (gain) with reference to DC voltage.
Av = (Output voltage fluctuation) / (Input offset fluctuation)
2.7 Supply Current (ICC)
Indicates the current that flows within the IC under specified no-load conditions.
2.8 Maximum Output Swing Bandwidth (Bom)
Indicates the range of frequency within which the maximum output voltage swing.
2.9 Unity Gain Frequency (f
T
)
Indicates the frequency where the voltage gain of Op-Amp is 1.
2.10 Gain Band Width (GBW)
Indicates to multiply by the frequency and the gain where the voltage gain decreases 6dB/octave.
2.11 Phase Margin (θ)
Indicates the margin of phase from 180 degree phase lag at unity gain frequency.
2.12 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)
2.13 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)
2.14 Equivalent Input Noise Voltage (Vn)
Indicates a noise voltage generated inside the operational amplifier reflected back to an ideal voltage source
connected in series with the input terminal.
2.15 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.
