Then input terminal voltage is set to more than VEE. *18 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. Ther efore, it is important to consider circui t protection measures, such as adding a f use, in case the IC is operated over the absolute maximum ratings.

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 betw een 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 – us e 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 part icular 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)

2.6 Large Signal Voltage Gain (Av)

The amplifying rate (gain) of the output voltage against the voltage differ ence 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)

www.rohm.com TSZ02201-0RAR0G200100-1-2 TSZ22111･15･001 BA3472xxx BA3472RFVM BA3474xxx BA3474RFV Operational Notes 1. Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. 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 bloc k from affecting the analog block. Furthermore, connect a capacitor to ground at all powe r 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 refe rence 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 exceed ed the rise in temperature of the chip may result in deterioration of the properties of the chip. The absolute maximum rating of the P D stated in this specification is when the IC is mounted on a 70mm x 70mm x 1.6mm glass epox y 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 ex pected 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 possi ble 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 dischar ge 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 ot her especially to ground, power supply and output pin. Inter-pin shorts could be due to many reasons such as me tal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few.

ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate safety measures including but not limited to fail-safe desi gn against the physical injury, damage to any property, which a failure or malfunction of our Products may cause. The following are examples of safety measures: [a] Installation of protection circuits or other protective devices to improve system safety [b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure 3. Our Products are designed and manufactured for use under standard conditions and not under any special or extraordinary environments or conditio ns, as exemplified below. Accordin gly, ROHM shall not be in any way responsible or liable for any damages, expenses or losses arising from the use of an y ROHM’s Products under any special or extraordinary environments or conditions. If you intend to use our Products under any special or extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: [a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents [b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust [c] Use of our Products in places where the Products ar e exposed to sea wind or corrosive gases, including Cl H2S, NH3, SO2, and NO2 [d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves [e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items [f] Sealing or coating our Products with resin or other coating materials [g] Use of our Products without cleaning residue of flux (ev en if you use no-clean type fluxes, cleaning residue of flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning residue after soldering [h] Use of the Products in places subject to dew condensation 4. The Products are not subject to radiation-proof design. 5. Please verify and confirm characteristics of the final or mounted products in using the Products. 6. In particular, if a transient load (a large amount of load applied in a short per iod of time, such as pulse. is applied, confirmation of performance characteristics after on-boar d mounting is strongly recomm ended. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability. 7. De-rate Power Dissipation (Pd) depending on Ambient temper ature (Ta). When used in sealed area, confirm the actual ambient temperature. 8. Confirm that operation temperat ure is within the specified range described in the product specification. 9.
