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) 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.
(2) Differential Input Voltage (V
ID
)
Indicates the maximum voltage that can be applied between non-inverting and inverting terminals without damaging
the IC.
(3) Input Common-mode Voltage Range (V
ICM
)
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.
(4) Power dissipation (P
D
)
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
(1) Input Offset Voltage (V
IO
)
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) Input Offset Current (I
IO
)
Indicates the difference of input bias current between the non-inverting and inverting terminals.
(3) Input Bias Current (I
B
)
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.
(4) Input Common-mode Voltage Range (V
ICM
)
Indicates the input voltage range where IC operates normally.
(5) Maximum Output Voltage (V
OM
)
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.
(6) Large Signal Voltage Gain (A
V
)
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)
(7) Supply Current (I
CC
)
Indicates the current that flows within the IC under specified no-load conditions.
(8) Output Source Current/ Output Sink Current (I
source
/ I
sink
)
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) Unity Gain Frequency (f
T
)
Indicates a frequency where the voltage gain of operational amplifier is 1.
(10) Gain Bandwidth (GBW)
Indicates to multiply by the frequency and the gain where the voltage gain decreases 6dB/octave.
(11) Phase Margin (θ)
Indicates the margin of phase from 180 degree phase lag at unity gain frequency.
(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)
(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)
(14) Input Referred Noise Voltage (V
N
)
Indicates a noise voltage generated inside the operational amplifier reflected back to an ideal voltage source
connected in series with the input terminal.
(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.
