Part Number:TL084
Hi,
I am outputing a PWM signal from controller , passing it through LPF and making it work like a DAC.
Step 2: Passing this output through a buffer (TL084)
Step 3: Amplifying the Output by Gain of 3 (TL084)
Problem: Stage 2 output (output of buffer) works well for higher voltage signals. But at signals below 2V it outputs a constant 1.96 volt (Ofset?/).
What should I do to get same output as input for signals less than 2V in Stage 2. (Vcc of opamp is +12V -Single Supply).
