Hi,
I'm looking for the datasheet of an old dual opamp (or might be a small audio power stage), DIL-14 package:
TCA490 (actually TCA490C)
It's a bit weird I'm asking this here since I should be pretty close to it myself (it's most likely made
by Philips, Signetics or Valvo) , but alas... only found a little circuit (below) and some brief specs.
Anyone happens to know more ?
Or can tell me what the Russion info in the pic below is actually saying ? I guess it's
about the gain, max. supply and power-consumption (as I found elsewhere already), but who knows there's more said.
Thanks !
Peter
