I'm trying to convert a 0-5V signal to 0-12V .
- The 0-5V is a 33KHz PWM coming out from an MCU
- I want to control a 4066 switch with it
I tried to use a 40106 to convert it from 5 to 12V. But, maybe because of the speed , 5V is below the 40106 threshold, so it didn't work..
Then I tried to amplify it with fets or bipolar transistors, the speed was satisfying only when a lot of current goes through the transistor..
The best solution I found was to use an fast op amp (lm833, there are faster chips, I'll try them too), but it's still not perfectly following the signal.
Let's say I want my pwm to have a 1% resolution, it's still 0,3µs, so it's quite speed...
Any solutions, ideas?
