Instructions for Using NJM2901N:

1. Supply Voltage:

   • Ensure the supply voltage (V_CC) is within the range of 4.5V to 16V.
   • Use a stable power supply to avoid fluctuations that can affect performance.

2. Quiescent Current:

   • The quiescent current is typically 0.8mA at 15V supply voltage. This is important for power budgeting in low-power applications.

3. Output Voltage Swing:

   • The output voltage swing is from 1.5V to 13.5V when V_CC is 15V and the load resistance is 1k惟. Ensure your load does not exceed this range to avoid distortion.

4. Input Bias Current:

   • The input bias current is typically 20nA at 15V supply voltage. This is crucial for high-impedance sources to minimize errors.

5. Input Offset Voltage:

   • The input offset voltage is typically 3mV at 15V supply voltage. This can affect the accuracy of the amplifier in precision applications.

6. Slew Rate:

   • The slew rate is typically 0.3V/渭s at 15V supply voltage. This limits the maximum rate of change of the output voltage and should be considered for high-frequency applications.

7. Common Mode Rejection Ratio (CMRR):

   • The CMRR is typically 80dB at 15V supply voltage and 1kHz frequency. This indicates the ability to reject common-mode signals, which is important for differential amplifiers.

8. Power Supply Rejection Ratio (PSRR):

   • The PSRR is typically 80dB at 15V supply voltage and 1kHz frequency. This indicates the ability to reject variations in the power supply, which is crucial for maintaining signal integrity.

9. Output Short-Circuit Protection:

   • The device has built-in short-circuit protection, allowing it to withstand continuous short circuits without damage. However, it is still recommended to use external protection components like fuses or current-limiting resistors in critical applications.

10. Layout Considerations:

    • Use bypass capacitors (typically 0.1渭F and 10渭F) close to the power supply pins to filter out noise and ensure stable operation.
    • Keep signal paths as short as possible to minimize noise and interference.

11. Storage and Handling:

    • Store the device in a dry, cool place to prevent moisture damage.
    • Handle with care to avoid static discharge, which can damage the internal components.

By following these parameters and instructions, you can ensure optimal performance and reliability of the NJM2901N operational amplifier in your circuits.
