Greetings,
I'm using tl072ip in a voltage follower as a TTL buffer.
The chip is powered by a 30V single supply.
The output during duty+ periods is correct, but not for duty- period.
During duty- periods, the value of the output is amplified close to the power supply voltage. I have attached the input and output waveform here.
I have tried 3 samples, the phenomenon was identical. The only issue I can find is the power supply. I have no idea can this chip only be operated in rail-rail conditions.
