Instructions for Using AD588KQ:

1. Supply Voltage (Vcc):

   • Ensure the supply voltage is within the range of 4.5V to 18V.
   • Use a stable power source to avoid fluctuations that could affect the reference voltage.

2. Output Voltage Range (Vout):

   • The output voltage can range from 0V to Vcc - 1.5V.
   • Design your circuit to ensure the load does not exceed this range.

3. Reference Voltage (Vref):

   • The reference voltage is nominally 5.000V at 25°C.
   • The initial accuracy is ±0.1% at 25°C, so calibrate your system accordingly.

4. Temperature Coefficient (Tc):

   • The temperature coefficient is ±10ppm/°C over the operating temperature range of -40°C to +85°C.
   • Consider thermal management to minimize temperature variations if high precision is required.

5. Line Regulation (ΔVref/ΔVcc):

   • The line regulation is 10ppm/V.
   • Ensure the supply voltage is stable to maintain the reference voltage accuracy.

6. Load Regulation (ΔVref/ΔIload):

   • The load regulation is 1ppm/mA.
   • Keep the output current within the specified range to avoid significant changes in the reference voltage.

7. Long-Term Stability (ΔVref/Δt):

   • The long-term stability is 10ppm/1000 hours at 25°C.
   • Periodically recalibrate your system to account for any drift over time.

8. Output Current (Iout):

   • The output current should be kept between -10mA and +10mA.
   • Exceeding these limits can damage the device or reduce its performance.

9. Operating Temperature Range (Toper):

   • The device operates reliably between -40°C and +85°C.
   • Avoid operating the device outside this range to prevent damage or reduced performance.

10. Handling and Storage:

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

By following these instructions, you can ensure optimal performance and reliability of the AD588KQ precision voltage reference.
