OPA4277: OPA4277UA - Is BB logo still used in this chip ?

BEE BEE NG

Part Number: OPA4277

Hello all,

Kindly advise, is BB logo (BB denote Burr Brown) still in TI Chips ? How do we determine which series are still using BB logo ? The acquisition of BB was way back 2000, why remain the use of BB logo ? Is the mentioned chip OPA4277 using BB logo ?

Appreciate a advise to the query.

Tks and Best regards,

The top left side of the IC molding should show \BB/ logo marking, however, I am unable to tell why it is marked in such. Perhaps the IC design was originated from BB company.

Many of BB audio ICs and designs are still marked with BB logo (a credit toward Burr-Brown's Innovation and development), so the markings on the newly manufactured ICs are no surprising.

It is important to make sure that TI ICs are purchased from TI authorized distributors or TI e-store. This will provide you with our product's traceability. There are many counterfeit parts on the market, and TI is unable to keep track all of these.

If you have additional questions, please let us know.

Best,

Raymond

Hi Bee Bee and hi Raymond,

"Burr-Brown" enjoys the highest reputation among independent experts and the "BB" logo stands for "State-Of-The-Art". TI is well-advised to maintain the "BB" logo
