Teledyne Philbrick opamp ?

Dear All

I am looking for info on a what I think is Teledyne-Philbrick opamp, in order to find a replacement.

This is a black plastic box ( 2 x 2 x 1 cm aprox.) with the markings Teledyne Philbrick 102001. I can send a picture, if needed.

Any info is appreciated.

Thanks in advance.

This is a hand-made discrete transistor op amp. Unless it is used in some exotic circuit, most likely it can be replaced with a pedestrian modern op-amp chip. I don't recognize that part #.

Hi Jon,

Tanks for the input. Someone else suggested the LF411A as a possible replacement. I think I'll try that one.

Most of their op amps IIRC started out with letters. Any other markings on it?

No, only 102001 on top and the number 7622 on one side

Hi Jorgen,

In fact, they had. I found the data sheet for the 1020 "ultra low offset drift OpAmp", with two models, 1020 and 1020-01 (mine). So the correct reference is

1020-01.

Tank you very much for your hint.

Regards
