OPA211: Can I use OPA211IDGKR in place of OPA211AIDGKR?

Part Number: OPA211

Hi,

I am working with a customer who is looking for OPA211AIDGKR the standard grade of this package, would I be able to recommend OPA211IDGKR instead since the part previously mentioned is out of stock? I saw that this is the high grade of this part and is the same package, but I want to make sure I am recommending something that will work for them in this instance before sending this back.

Thanks,

Sam

    Hi Sam,

    You are correct, the OPA211AIDGKR is the standard grade and OPA211IDGKR is the high-grade on the VSSOP (DGK) 8 package. These devices have the same package and pin out. The difference is in the offset, offset drift and PSRR specifications, where the high-grade offers the tighter spec and higher accuracy. The bandwidth, slew rate and noise performance are identical.

    Yes, from the circuit performance perspective, replacing a standard grade device with the high grade will not create any issues, as long as the high-grade cost can be afforded.

    Thank you and Regards,
