Datasheet
Description of Electrical Characteristics
Described below are descriptions of the relevant electrical terms used in this datasheet. Items and symbols used are also
shown. Note that item name and symbol and their meaning may differ from those on another manufacturer’s document or
general document.
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 (VDD/VSS)
Indicates the maximum voltage that can be applied between the VDD terminal and VSS 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 and inverting terminals without damaging
the IC.
1.3 Input Common-mode Voltage Range (Vicm)
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.
1.4 Power dissipation (Pd)
Indicates the power that can be consumed by the IC when mounted on a specific board at the ambient temperature 25C
(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
2.1 Input Offset Voltage (Vio)
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.
2.2 Input Offset Current (Iio)
Indicates the difference of input bias current between the non-inverting and inverting terminals.
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
the non-inverting and inverting terminals.
2.4 Supply Current (IDD)
Indicates the current that flows within the IC under specified no-load conditions.
2.5 Maximum Output Voltage(High) / Maximum Output Voltage(Low) (VOH/VOL)
Indicates the voltage range of the output under specified load condition. It is typically divided into maximum output
voltage High and low. Maximum output voltage high indicates the upper limit of output voltage. Maximum output
voltage low indicates the lower limit.
2.6 Large Signal Voltage Gain (Av)
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)
2.7 Input Common-mode Voltage Range (Vicm)
Indicates the input voltage range where IC normally operates.
2.8 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)
2.9 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)
2.10 Output Source Current/ Output Sink Current (Isource / Isink)
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.
2.11 Slew Rate (SR)
Indicates the ratio of the change in output voltage with time when a step input signal is applied.
2.12 Gain Band Width (GBW)
The product of the open-loop voltage gain and the frequency at which the voltage gain decreases 6dB/octave.
2.13 Unity Gain Frequency (fT)
Indicates a frequency where the voltage gain of operational amplifier is 1.
2.14 Phase Margin (θ)
Indicates the margin of phase from 180 degree phase lag at unity gain frequency.
2.16 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.
2.12 Channel Separation (CS)
Indicates the fluctuation in the output voltage of the driven channel with reference to the change of output voltage of
the channel which is not driven.

●Application example
○Voltage follower
Voltage gain is 0dB.
Using this circuit, the output voltage (OUT) is configured
to be equal to the input voltage (IN). This circuit also
stabilizes the output voltage (OUT) due to high input
impedance and low output impedance. Computation for
output voltage (OUT) is shown below.
OUT=IN
VDD
OUT
IN
VSS
Figure 52. Voltage follower
○Inverting amplifier
For inverting amplifier, input voltage (IN) is amplified by
a voltage gain and depends on the ratio of R1 and R2.
The out-of-phase output voltage is shown in the next
expression
OUT=-(R2/R1)・IN
This circuit has input impedance equal to R1.
Figure 53. Inverting amplifier circuit
○Non-inverting amplifier
R1
R2
VDD
OUT
For non-inverting amplifier, input voltage (IN) is
amplified by a voltage gain, which depends on the ratio
of R1 and R2. The output voltage (OUT) is in-phase
with the input voltage (IN) and is shown in the next
expression.
OUT=(1 + R2/R1)・IN
Effectively, this circuit has high input impedance since
its input side is the same as that of the operational
amplifier.

●Power Dissipation
Power dissipation (total loss) indicates the power that the IC can consume at Ta=25C (normal temperature). As the IC
consumes power, it heats up, causing its temperature to be higher than the ambient temperature. The allowable
temperature that the IC can accept is limited. This depends on the circuit configuration, manufacturing process, and
consumable power.
Power dissipation is determined by the allowable temperature within the IC (maximum junction temperature) and the
thermal resistance of the package used (heat dissipation capability). Maximum junction temperature is typically equal to the
maximum storage temperature. The heat generated through the consumption of power by the IC radiates from the mold
resin or lead frame of the package. Thermal resistance, represented by the symbol θjaC/W, indicates this heat dissipation
capability. Similarly, the temperature of an IC inside its package can be estimated by thermal resistance.
Figure 55. (a) shows the model of the thermal resistance of a package. The equation below shows how to compute for the
Thermal resistance (θja), given the ambient temperature (Ta), maximum junction temperature (Tjmax), and power
dissipation (Pd).
θja = (Tjmax-Ta) / Pd C/W
・・・・・ (Ⅰ)
The Derating curve in Figure 55. (b) indicates the power that the IC can consume with reference to ambient temperature.
Power consumption of the IC begins to attenuate at certain temperatures. This gradient is determined by Thermal
resistance (θja), which depends on the chip size, power consumption, package, ambient temperature, package condition,
wind velocity, etc. This may also vary even when the same of package is used. Thermal reduction curve indicates a
reference value measured at a specified condition. Figure 56. (c) to (d) shows an example of the derating curve for BU7291,
BU7291S, BU7294, BU7294S.

●Operational Notes
1) Absolute maximum ratings
Absolute maximum ratings are the values which indicate the limits, within which the given voltage range can be safely
charged to the terminal. However, it does not guarantee the circuit operation.
2) Applied voltage to the input terminal
For normal circuit operation of voltage comparator, please input voltage for its input terminal within input common mode
voltage VDD + 0.3V. Then, regardless of power supply voltage,VSS - 0.3V can be applied to input terminals without
deterioration or destruction of its characteristics.
3) Power supply (single / dual)
The op-amp operates when the voltage supplied is between VDD and VSS.
Therefore, the single supply op-amp can be used as 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 including
reduced current capability due to the rise of chip temperature. 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
Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong orientation
or if pins are shorted together. Short circuit may be caused by conductive particles caught between the pins.
6) Short-circuit between pins and erroneous mounting
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
7) IC handling
Applying mechanical stress to the IC by deflecting or bending the board may cause fluctuations in the electrical
characteristics due to piezo resistance effects.
8) 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, make sure 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.
9) Output capacitor
If a large capacitor is connected between the output pin and VSS pin, current from the charged capacitor will flow into the
output pin and may destroy the IC when the VDD pin or VIN pin is shorted to ground or pulled down to 0V. Use a
capacitor smaller than 0.1μF between output pin and VSS pin.
10) Oscillation by output capacitor
Please pay attention to the oscillation by output capacitor and in designing an application of negative feedback loop
circuit with these ICs.
11) Latch up
Be careful of input voltage that exceed the VDD and VSS. When CMOS device have sometimes occur latch up and
protect the IC from abnormaly noise.
