old Burr Brown Op Amps

What is inside those BB opamps ? Discrete ? Any good ?

The equipment where I found those inside had a bandwith > 200 kHz

The Burr-Brown "Discontinued Products" sheet lists the OPA602AM as a replacement for the 3308/12C.

I found the discontinued products sheet here:

Unisonic is a modern dual opamp with single supply, that BB is single opamp with dual voltage supply.

I think I will try it just for fun. The pcb on the picture is a complete line buffer with discrete output stage inside feedback loop.

This is a hybrid. Thus the insides are discrete components on a substrate which is then potted.
