Hello,

My customer is considering to use AD8512 at a single power supply, so they need to know additional specifications of AD8512.

Q1) Would you let me know the Max. supply voltage of AD8512 at single poer supply (+, GND)?

Q2)Would you let me know the  Common mode voltage range of AD8512  at single poer supply (+, GND)?

As a graph of  Figure 13 in datasheet, can AD8512 support over 30V?

Regards,
Se-woong

• Hi Se-woong,

Thank you for considering analog devices parts for your application. See below for the answers to your question.

Q1) Would you let me know the Max. supply voltage of AD8512 at single power supply (+, GND)?

For single supply operation AD8512 can be operated at +Vs = 30V and -Vs = GND.

Q2)Would you let me know the  Common mode voltage range of AD8512  at single power supply (+, GND)?

Please refer to the ±15V specification table of the part. As a rule of thumb most of the op amps rails can be adjusted to any voltage level as long as the difference between them is within the specified limits given on the datasheet. For your application which is 30V single supply you new input voltage range will be +1.5V to +28V.

As a graph of  Figure 13 in datasheet, can AD8512 support over 30V?

The absolute maximum rating of the device is ±18 V or 36V single supply. We do not recommend operating the device near this level as it will induce stress to the product that may cause permanent damage, and for it to cause to behave out of the indicated specifications.

Let me know if you have any clarifications. I hope this helped.

Best Regards,
Goz
