SOLVED!    The cause of overheating of LM1206 was imbalance between compensating capacitance and output capacitance, that is the capacitive load was too high. I replaced 10nF compensating capacitor with a larger one (tried both 100nF and even 680nF - they are ok) and all problems were...

I'll try to physically shorten feedback loop and experiment with shutdown pin in LT1206. The original tangensoft circuit contains 22k resistor that bridges S/D pin with op-amp output. Most of the designs omit reducing quiescent current and directly connect S/D pin with -V. Anyway, analyzing...

Hello everyone! This is my first post in this forum, so please be gentle ;-) I recently came across cmoy amp and lt1206-based virtual ground circuit. It caught my attention, so I built it from scratch and i don't understand why LT1206 is overheating (after several seconds of operation i can't...
