    I bought 3 CA3080's a while back and wanted to order another 10 for future projects since they are hard to come by, however the supplier doesn't have any more (bigbear) so i was wondering if i can use one half of an LM13600 instead?

    sorry...i mean smallbear.

    You will find this read educational:

    Basically, an LM13600/LM13700 is a pair of CA3080s with an added (optional) Darlington buffer on the output.

    @ SgtWookie: Could I ask a question on the OPs behalf please, in case he has not spotted this issue. What should be done with the linearising diodes present on the LM13600 inputs, but absent on the CA3080? Should they be left floating, or used in some way?

    Regards Adjuster
