●Derating curves
Power dissipation(total loss) indicates the power that can be consumed by IC at Ta=25℃(normal temperature).IC is heated
when it consumed power, and the temperature of IC chip becomes higher than ambient temperature. The temperature that
can be accepted by IC chip depends on circuit configuration, manufacturing process, and consumable power is limited.
Power dissipation is determined by the temperature allowed in IC chip (maximum junction temperature) and thermal
resistance of package (heat dissipation capability). The maximum junction temperature is typically equal to the maximum
value in the storage temperature range. Heat generated by consumed power of IC radiates from the mold resin or lead frame
of the package. The parameter which indicates this heat dissipation capability(hardness of heat release)is called thermal
resistance, represented by the symbol θja[℃/W].The temperature of IC inside the package can be estimated by this thermal
resistance. Fig.51(a) shows the model of thermal resistance of the package. Thermal resistance θja, ambient temperature
Ta, junction temperature Tj, and power dissipation Pd can be calculated by the equation below
θja = (Tj-Ta) / Pd
[℃/W]
・・・・・ (Ⅰ)
Derating curve in Fig.51(b) indicates power that can be consumed by IC with reference to ambient temperature. Power that
can be consumed by IC begins to attenuate at certain ambient temperature. This gradient is determined by thermal
resistance θja. Thermal resistance θja depends on chip size, power consumption, package, ambient temperature, package
condition, wind velocity, etc even when the same of package is used. Thermal reduction curve indicates a reference value
measured at a specified condition. Fig.52(c),(d) show a derating curve for an example of BA2903Y, BA2901Y.

●Description of electrical characteristics
Described below are descriptions of the relevant electrical terms.
Please note that item names, symbols, and their meanings 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 characteristics 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 power supply terminals
without causing deterioration of the electrical characteristics or destruction of the internal circuitry.
1.2 Differential input 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 electrical characteristics or damage to the IC itself. Normal operation is not guaranteed within the
input 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 temperature, the lower the power consumption of the IC. The storage temperature range denotes the range
of temperatures the IC can be stored under without causing excessive deterioration of the electrical characteristics.
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 maximum junction temperature and the 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 setting the output voltage to 0V.
2.2 Input offset current (Iio)
Indicates the difference of the input bias current between the non-inverting and inverting terminals.
2.3 Input bias current (Ib)
Denotes the current that flows into or out of the input terminal, it is defined by the average of the input bias current at
the non-inverting terminal and the input bias current at the inverting terminal.
2.4 Input common-mode voltage range (Vicm)
Indicates the input voltage range under which the IC operates normally.
2.5 Large signal voltage gain (AV)
The amplifying rate (gain) of the output voltage against the voltage difference between the non-inverting and inverting
terminals, it is (normally) the amplifying rate (gain) with respect to DC voltage.
AV = (output voltage fluctuation) / (input offset fluctuation)
2.6 Circuit current (ICC)
Indicates the current of the IC itself that flows under specific conditions and during no-load steady state.
2.7 Output sink current (IOL)
Denotes the maximum current that can be output under specific output conditions.
2.8 Output saturation voltage low level output voltage (VOL)
Signifies the voltage range that can be output under specific output conditions.
2.9 Output leakage current, High level output current (Ileak)
Indicates the current that flows into the IC under specific input and output conditions.
2.10 Response time (Tre)
The interval between the application of input and output conditions.

●Notes for use
1) Unused circuits
VCC
When there are unused circuits it is recommended that they be
connected as in Fig.53, setting the non-inverting input terminal to a
potential within the in-phase input voltage range (VICR).
+
OPEN
2) Input terminal voltage
－
Please keep this
potential in Vicm
Applying VEE + 36V to the input terminal is possible without causing
deterioration of the electrical characteristics or destruction, irrespective
of the supply voltage. However, this does not ensure normal circuit
operation. Please note that the circuit operates normally only when the
input voltage is within the common mode input voltage range of the
electric characteristics.
VEE
(Vicm＞VEE)
Fig. 53 Disable circuit example
3) Power supply (signal / dual)
The op-amp operates when the specified voltage supplied is between VCC and VEE. Therefore, the signal supply op-amp
can be used as a dual supply op-amp as well.
4) Power dissipation Pd
Using the unit in excess of the rated power dissipation may cause deterioration in electrical characteristics due to a rise in
chip temperature, including reduced current capability. Therefore, please take into consideration the power dissipation
(Pd) under actual operating conditions and apply a sufficient margin in thermal design. Refer to the thermal derating
curves for more information.
5) Short-circuit between pins and erroneous mounting
Incorrect mounting may damage the IC. In addition, the presence of foreign particles between the outputs, the output and
the power supply, or the output and GND may result in IC destruction.
6) Terminal short-circuits
When the output and VCC terminals are shorted, excessive output current may flow, resulting in undue heat generation
and, subsequently, destruction.
7) Operation in a strong electromagnetic field
Operation in a strong electromagnetic field may cause malfunctions.
8) Radiation
This IC is not designed to withstand radiation.
9) IC handing
Applying mechanical stress to the IC by deflecting or bending the board may cause fluctuations in the electrical
characteristics due to piezoelectric (piezo) effects.
10) Board inspection
Connecting a capacitor to a pin with low impedance may stress the IC. Therefore, discharging the capacitor after every
process is recommended. In addition, when attaching and detaching the jig during the inspection phase, ensure that the
power is turned off before inspection and removal. Furthermore, please take measures against ESD in the assembly
process as well as during transportation and storage
