Part Number: OPA657
Other Parts Discussed in Thread: OPA818,

Hi,

The following thread introduces OPA818 as an alternative to OPA657.

https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1356878/opa657-alternative-needed

However, customers are looking for ICs with the same pin function package as OPA657U.

Do you have this product?

Or is there a future release plan?

Best Regards,

Nishie

Hi Yuta,

Below is a list of devices with similar specs as the OPA657U in the same package and pinouts. There are some on the list with NULL pins or a shutdown pin, however these pins can be left unconnected. Depending if the customer is grounding or biasing the NC pins on the OPA657U, this might result in one of these amplifiers also not working. I would also like to add that the only FET input device on the list is the OPA657U.
