●Description of Electrical Characteristics
Described below are descriptions of the relevant electrical terms
Please note that item names, symbols and their me anings may differ from those on another manufacturer’s documents.
1. Absolute maximum ratings
The absolute maximum ratings are values that should never be exceeded, since doing so may result in deterioration of
electrical chara c teristics or damage to the part itself as well as peripheral components.
1.1 Power supply voltage (VCC-VEE)
Expresses the maximum voltage that can be supplied between the positive and negative supply terminals without
causing deterioration of the electrical characteristics or destruction of the internal circuitry.
1.2 Differential inp ut voltage (Vid)
Indicates the maximum voltage that can be supplied between the non-inverting and inverting terminals without
damaging the IC.
1.3 Input common-mode voltage range (Vicm)
Signifies the maximum voltage that can be supplied to non-inverting and inverting terminals without causing
deterioration of the characteristics or damage to the IC itself. Normal operation is not guaranteed within the
common-mode voltage range of the maximum ratings - use within the input common-mode voltage range of the
electric characteristics instead.
1.4 Operating and storage temperature ranges (Topr,Tstg)
The operating temperature range indicates the temperature range within which the IC can operate. The higher the
ambient temperat ure, the lower t he power consumpt ion of the IC. The storage temperatu re range denot es the range
of temperatures the IC can be stored under without causing excessive deterioration of the electrical characterist ics.
1.5 Power dissipation (Pd)
Indicates the power that can be consumed by a particular mounted board at ambient temperature (25℃). For
packaged products, Pd is determined by the maximum ju nction temperature and t he thermal resistance.
2. Electrical characteristics
2.1 Input offset voltage (Vio)
Signifies the voltage difference between the non-inverting and inverting terminals. It can be thought of as the input
voltage difference required for sett i ng the output voltage to 0 V.
2.2 Input offset voltage drift ( △Vio/△T)
Denotes the ratio of the input offset voltage fluctuation to the ambient temperature fluctuation.
2.3 Input offset current (Iio)
Indicates the difference of in put bias current between the non-inverting and inverting terminals.
2.4 Input offset current drift ( △Iio/△T)
Signifies the rati o of the input offset current fluctuation to the ambient temperature fluctuation.
2.5 Input bias current (Ib)
Denotes the current that flows into or out of the input terminal, it is defined by the av erage of the input bias current at
the non-inverting terminal and the input bias current at the inverting terminal.
2.6 Circuit current (ICC)
Indicates the current of the IC itself that flows under specified conditions and duri ng no-load steady state.
2.7 High level output voltage/low level output voltage (VOH/VOL)
Signifying th e voltage range that can be out put under specif ied load cond itions, it is in ge neral divided in to high level
output voltage and low level out put voltage. High level output voltage indicates the upp er limit of the output voltage,
while low level output voltage the lower limit.
2.8 Large signal vo ltage gain (AV)
The amplifying rate (gain) of the output voltage against the voltage difference between non-inverting and inverting
terminals, it is (normally) the a m plifying rate (gain) with respect to DC voltage.
AV = (output voltage fl uctuation) / (input offset fluct uation)
2.9 Input common-mode voltage range (Vicm)
Indicates the input voltage range under which the IC operates normally.
