API 2520 OpAmp
Please Note:
Due to the increasing amount of non API 2520 style op-amps, to protect the proprietary design of our discrete components, and to precisely match and track their use and performance, API has started to serialize each 2520 op-amp with tamper proof labels.
Unique serial number is the proof that op-amp is genuine and customers are welcome to inquire about each op-amp they own, or plan to purchase.
To get an op-amp 2520 order approved, please have the faulty unit serial numbers ready together with the photo of each op-amp.
This photo needs to show the production date stamp (or the original serial number label) and the pins need to be clipped off completely.
