There are four different versions of this chip NE602,NE612,SA602 and SA612.From what I understand the main difference between NE and SA is that SA has extended temperature range (primarily made for military use I guess).For normal indoor hobby projects NE are most likely sufficient.NE602 colpitts oscillator construction challenge ?!! All NE602 Experiments#0183;Details about the NE602 and NE612 mention ability to generate AM,but I was assuming these ICs are meant to produce double sideband (DSB-SC,no carrier) by default.And I assumed that it would be necessary to somehow follow some procedure to offset the message with a DC voltage in order to then generate AM.
