Does anyone have an idea how to make a circuit between the two devices as in the picture?
I have a PWM source which operates from 0 -2.5-5v and analog devices to the entrance between the input and GND has 5V and then output either 10V when you connect a short input and GNG have + 10v
2.5v = 0V
at the exit of how to do to merge these two assembly
greeting
Some filtering turns the PWM into an analog value. Then one (or a few) op-amps can amplify, invert and offset the 0 to 5 volts to 10 to -10 volts.
The trick though is getting a sensible output when the input is not running. If the PWM is off, what should the output voltage be, considering safe operation?
Yes , you can use a simple RC filer on the pwm then a differential opamp to offset and double the voltage
You have the PIC output a delayed enable to the amplifier to only turn it on when its stable. Thats what i do on my step2linearQuote:
