ADA4522 USE OF LARGE SOURCE RESISTANCE

Category: Hardware
Product Number: ADA4522

Hello
In the "USE OF LARGE SOURCE RESISTANCE" chapter of the ADA4522 datasheet, it states "When the ADA4522-1/ADA4522-2/ADA4522-4 are configured in a unity-gain follower configuration with a large source resistance and slow power supply ramp rate, The amplifier output may rail to the positive supply."
How much should I consider for the ramp rate?

Best regards

  • Hi   san,

    Power up positive supply first or at the same time as negative supply AND slew rate faster than 2.2V/ms.

    This was based on the previous bench test that was done on this device.
