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 25C (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 Unity Gain Frequency (fT) Indicates a frequency where the voltage gain of operational amplifier is 1. 2.13 Phase Margin (θ) Indicates the margin of phase from 180 degree phase lag at unity gain frequency. 2.14 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. 2.15 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. www.rohm.com © 2013 ROHM Co., Ltd.

Inverting amplifier circuit ○Non-inverting amplifier R1 R2 VDD OUT IN VSS 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. Figure 77.

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 θjaC/W, indicates this heat dissipation capability. Similarly, the temperature of an IC inside its package can be estimated by thermal resistance. Figure 78. (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 78. (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 79.

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. Connect to Vicm Vicm VSS Figure 80. Example of application circuit for unused op-amp 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) Operation in a strong electromagnetic field 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 of 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 VCC pin is shorted to ground or pulled down to 0V. Use a capacitor smaller than 0.1uF 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. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.
