NJM4558 Instructions

1. Supply Voltage:

   • The NJM4558 can operate from a single supply voltage ranging from 2.0V to 32V or a dual supply voltage ranging from 卤1.0V to 卤16V.
   • Ensure the supply voltage is within the specified range to avoid damage to the device.

2. Input Voltage:

   • The input voltage should be within the range of -14V to +14V when using a 卤15V supply.
   • Avoid exceeding the input voltage limits to prevent distortion or damage.

3. Output Voltage:

   • The output voltage swing is typically 卤13.5V with a load resistance of 2k惟 when using a 卤15V supply.
   • For optimal performance, ensure the load resistance is appropriate for the desired output swing.

4. Slew Rate:

   • The slew rate of the NJM4558 is 0.3V/渭s, which limits the maximum rate of change of the output voltage.
   • This parameter is important for applications involving high-frequency signals.

5. Gain Bandwidth Product:

   • The gain bandwidth product (GBP) is 1.0MHz, indicating the product of the open-loop gain and the frequency at which it is measured.
   • Use this parameter to determine the stability and performance of the op-amp in different configurations.

6. Common Mode Rejection Ratio (CMRR):

   • The CMRR is 80dB, which measures the ability of the op-amp to reject common-mode signals.
   • Higher CMRR values indicate better rejection of common-mode noise.

7. Power Supply Rejection Ratio (PSRR):

   • The PSRR is 80dB, which measures the ability of the op-amp to reject variations in the power supply voltage.
   • Higher PSRR values indicate better stability under varying power supply conditions.

8. Quiescent Current:

   • The quiescent current is 1.8mA, which is the current drawn by the op-amp when no signal is applied.
   • This parameter is important for power consumption considerations in battery-powered applications.

9. Pin Configuration:

   • Pin 1: Offset Null (not used in standard applications)
   • Pin 2: Inverting Input (IN-)
   • Pin 3: Non-Inverting Input (IN+)
   • Pin 4: Negative Supply (V_SS)
   • Pin 5: Output (OUT)
   • Pin 6: Not Used
   • Pin 7: Positive Supply (V_CC)
   • Pin 8: Output (OUT) for the second op-amp
   • Pin 9: Non-Inverting Input (IN+) for the second op-amp
   • Pin 10: Inverting Input (IN-) for the second op-amp
   • Pin 11: Offset Null (not used in standard applications)
   • Pin 14: Negative Supply (V_SS) for the second op-amp

10. Mounting and Handling:

    • Handle the NJM4558 with care to avoid static discharge, which can damage the device.
    • Follow proper soldering techniques to ensure reliable connections and prevent thermal damage.

11. Storage:

    • Store the NJM4558 in a dry, cool place to prevent moisture damage.
    • Keep the device in its original packaging until ready for use.

By following these instructions and parameters, you can ensure optimal performance and reliability of the NJM4558 in your circuits.
