OPA2810: Is there any chip can replace AD8066?

Part Number: OPA2810
Other Parts Discussed in Thread: OPA2863A

Hi TIer

When I recommend the customer to use OPA2810 replace AD8066. customer concern the cooling capacity of OPA2810.

Customer prefer the chip with thermal pad.

So could you provide me with a more suitable replacement material with thermal pad?

Thank you very much!

    Hi Yuxi,

    The AD8066 isn't offered in a package with thermal pad either. Is there a concern with the cooling capacity of the OPA2810 vs AD8066?

    We have other devices like the OPA2863A which are offered in a package with thermal pad (3x3mm DSN-10 with thermal pad). Please share the key specifications required for this application and why is there a need for the thermal pad so we can run a comprehensive search and suggest the best available options.

    Regards,

    yes , AD8066 is not offered thermal pad. Customer need good cooling capacity, they do not test OPA2810.

    how to filter the chip which offer thermal pad on ti.com?

    I do not find this filter setting.

    Hi Yuxi,

    There is no direct way to filter out devices with a power pad using the parametric search table. We need to either search by package (if a certain package is known to have a power pad) or go through the datasheets to find this out.

    For this requirement, I see the THS4032DGN and OPA2863ADSN as two potential options:

    1. The THS4032DGN is a 220 MHz. GBW, low-noise, 32 V voltage feedback amplifier.

    2. The OPA2863ADSN is a 50 MHz, RRIO, low-power, voltage feedback amplifier with very high precision of max. 1.2 uV/C offset drift and max. 95 uV offset.

    Would any of these devices meet the customer's requirements?

    Regards,
