  • Operational Notes 1) Unused circuits When there are unused circuits it is recommended that they are connected as in Figure 34., setting the non-inverting input terminal to a potential within input common-mode voltage range (Vicm). 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 specif ied voltage supplied is between VDD and VSS. Therefore, the si ngle 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 due to a rise in chip temperature, including reduced current capability. Theref ore, 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 betwe en the outputs, the output and the power supply, or the output and GND may result in IC destruction. 6) Operation in a str ong electromagnetic field Operation in a strong electromagnetic field may cause malfunctions. 7) IC handling Applying mechanical stress to the IC by deflecting or bending the board may cause fluct uations in the electrical characteristics due to piezo resistance effects. 8) Board inspection Connecting a capacitor to a pin with low impedance may stre ss the IC. Therefore, discharging the capacitor after every process is recommended. In addition, when attaching and detac hing the jig during the inspec tion phase, ensure that the power is turned OFF before inspection and removal. Furthe rmore, please take measures against ESD in the assembly process as well as during transportation and storage. 9) 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. Designed negative feedback circuit using this IC, verify output oscillation caused by capacitive load. 10) Latch up Be careful of input voltage that exceed the VDD and VSS. When CMOS device have sometimes occur latch up operation. And protect the IC from abnormaly noise 11) Decupling capacitor Insert the decupling capacitance between VDD and VSS, for stable operation of operational amplifier. 12) Shutdown Terminal The shutdown terminal can’t be left unconnected. In case shutdown operation is not needed, the shutdown pin should be connected to VDD when the IC is used. Leaving the shutdown pin floating will result in an undefined operation mode, either shutdown or active, or even oscillating between the two modes. Connect to Vicm Figure. 34.
