OPA2277: How to replace OPA2277

user4499359

Part Number: OPA2277
Other Parts Discussed in Thread: DAC8563, OPA2191, OPA2333P

Dear team:
I have a circuit DAC8563, the two outputs use OPA2277 for output buffering, no amplification. Now I want to choose a two-channel small-sized op amp or two single-channel small-size op amps. Can you recommend one?
Thank you.

The op amp is powered by 5V.

The package size is large, I want to use a small size.

Hello User,

I can help you. I found 2 options for you to take a look at:

OPA2191: available in a 3mm x 3mm VSSOP package
OPA2333P: available in a 2mm x 2mm WSON package

Let me know your thoughts.
