Mounted on a FR4 glass epoxy 2 layers PCB 70mm×70mm×1.6mm (occupied copper area：15mm×15mm). Mounted on a FR4 glass epoxy 2 layers PCB 70mm×70mm×1.6mm (occupied copper area：70mm×70mm). Mounted on a FR4 glass epoxy 4 layers PCB 70mm×70mm×1.6mm (occupied copper area：70mm×70mm). The voltage difference between inverting input and non-inverting input is the differential input voltage. Then input terminal voltage is set to more than VEE. An excessive input current will flow when input voltages of less than VEE-0.6V are applied. The input current can be set to less than the rated current by adding a limiting resistor. Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. www.rohm.com © 2012 ROHM Co., Ltd.

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 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 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 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 junction temperature and the thermal resistance. 2. Electrical Characteristics 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 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 current at non-inverting terminal and input bias current at inverting terminal. 2.4 Circuit Current (ICC) Indicates the current of the IC itself that flows under specified conditions and during no-load steady state. 2.5 Maximum Output Voltage(High) / Maximum Output Voltage(Low) (VOH/VOL) Indicates the voltage range that can be output by the IC 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) The amplifying rate (gain) of the output voltage against the voltage difference between non-inverting and inverting terminals, it is (normally) the amplifying rate (gain) with respect to DC voltage. AV = (output voltage fluctuation) / (input offset fluctuation) 2.7 Input Common-mode Voltage Range (Vicm) Indicates the input voltage range under which the IC operates normally. 2.8 Common-mode Rejection Ratio (CMRR) Indicates the ratio of fluctuation of input offset voltage when in-phase input 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 under specific output conditions, it is divided into output source current and output sink current. The output source current indicates the current flowing out of the IC, and the output sink current the current flowing into the IC. 2.11 Unity Gain Frequency (fT) Indicates a frequency where the voltage gain of operational amplifier is 1. 2.12 Gain Bandwidth (GBW) Indicates to multiply by the frequency and the gain where the voltage gain decreases 6dB/octave. 2.13 Slew Rate (SR) SR is a parameter that shows movement speed of operational amplifier. It indicates rate of variable output voltage as unit time. 2.14 Channel Separation (CS) Indicates the fluctuation of input offset voltage or that of output voltage with reference to the change of output voltage of driven channel. www.rohm.com © 2012 ROHM Co., Ltd.

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. Figure 52. (a) shows the model of thermal resistance of the package. Thermal resistance θja, ambient temperature Ta, maximam junction temperature Tjmax, and power dissipation Pd can be calculated by the equation below: θja = (Tjmax-Ta) / Pd ℃/W Derating curve in Figure 52. (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 iis 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. Figure 52. (c) to (f) shows a derating curve for an example of BA3472, BA3474, BA3472R, BA3474R.

Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply pins. 2. Power Supply Lines Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. 3. Ground Voltage Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. 4. Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground traces should be routed separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance. 5. Thermal Consideration Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. The absolute maximum rating of the PD stated in this specification is when the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the PD rating. 6. Recommended Operating Conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. 7. Inrush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. 8. Operation Under Strong Electromagnetic Field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 9. Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 10. Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin. Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few. www.rohm.com © 2012 ROHM Co., Ltd.

Regarding the Input Pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode or transistor. For example (refer to figure below): When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided. Figure 53. Example of monolithic IC structure 12. Unused Circuits When there are unused circuits it is recommended that they are connected as in Figure 54, setting the non-inverting input terminal to a potential within input common-mode voltage range (Vicm). Keep VCC this potential in Vicm 13. Input Terminal Voltage Applying GND + 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. 14. Power Supply (Single / Dual) The op-amp operates when the specified voltage supplied is between VCC and VEE. Therefore, the single supply op-amp can be used as dual supply op-amp as well. + VEE Figure 54. The Example of Application Circuit for Unused Op-amp 15. 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. 16. Output Capacitor Discharge of the external output capacitor to VCC is possible via internal parasitic elements when VCC is shorted to VEE, causing damage to the internal circuitry due to thermal stress. Therefore, when using this IC in circuits where oscillation due to output capacitive load does not occur, such as in voltage comparators, use an output capacitor with a capacitance less than 0.1µF. www.rohm.com © 2012 ROHM Co., Ltd.
