Electronic circuit PWM Analog Output

I used the below circuit to generate high current analog output (0-10V) from PWM input by changing the duty cycle of the PWM. It works well when I use 5V PWM that comes from Atmega8 microcontroller.

See Drawing One

However, using the same circuit with 3.3V PWM that comes from ESP8266, it does NOT work. It gives only 2V output.

See Drawing Two

Could you please make similar board in your bench and let me know how to solve it

This is a current buffer circuit, if you decrease the input voltage, you will need to adjust the gain. Moreover, if you have 2V on Vout, it's mean that PWM frequency is much higher than RC Low pass filter frequency cut 更多
