Richard:
For low bandwidth signals you may be able to make the analogue output by using a timer to produce a PWM signal that you vary the duty cycle according to desired analogue value. Then filter the PWM voltage into an analogue value with an low pass filter. Best situation since the analogue wants to be an output fed off someplace else is to use an op-amp to buffer out the signal. The filter could simply be an R/C circuit followed by the op-amp as a simple buffer. More complex op-amp configurations as a low pass filter could also be used. Michael Karas |
