Instructions for Use:

  1. Supply Voltage:

    • Ensure the supply voltage is within the range of -16V to +16V.
    • The device can operate with a single or dual supply.
  2. Input Voltage:

    • The input voltage should be within the range of -14V to +14V relative to ground.
    • Avoid exceeding these limits to prevent damage to the device.
  3. Output Voltage Swing:

    • The output voltage swing is typically -13V to +13V under no load conditions.
    • Load resistance will affect the actual output swing.
  4. Output Current:

    • The maximum continuous output current is ±10mA.
    • Exceeding this limit may cause the device to overheat or fail.
  5. Input Bias and Offset Currents:

    • The input bias current and input offset current are very low, typically within ±50nA and ±10nA, respectively.
    • These parameters are important for high-impedance applications.
  6. Input Offset Voltage:

    • The input offset voltage is typically within ±2mV.
    • This parameter affects the accuracy of the amplifier in precision applications.
  7. Common-Mode Rejection Ratio (CMRR):

    • The CMRR is high, typically between 80dB and 100dB at 0.1Hz.
    • This indicates good rejection of common-mode signals.
  8. Power Supply Rejection Ratio (PSRR):

    • The PSRR is also high, typically between 80dB and 100dB at 0.1Hz.
    • This helps maintain stable output even with power supply variations.
  9. Slew Rate:

    • The slew rate is typically 0.5V/μs.
    • This parameter is important for high-frequency applications.
  10. Bandwidth:

    • The bandwidth is typically 1.5MHz for a 1V peak-to-peak output.
    • Higher output levels will reduce the bandwidth.
  11. Quiescent Current:

    • The quiescent current is typically 2mA at ±15V supply.
    • This is the current drawn by the device when it is not driving any load.

Additional Notes:

  • Stability:
    • Use appropriate feedback networks to ensure stability, especially at higher frequencies.
  • Temperature:
    • The device is designed to operate over a wide temperature range, but performance parameters may vary.
  • Handling:
    • Handle the device with care to avoid static damage. Use proper ESD protection during handling and installation.
