How to convert 15VPWM (frequency 5K) wave signal into 5VTTL signal through optical coupler? What type of optical coupler should I choose? Ask someone for help. Thank you!
If the frequency is very high (20K~ 1MHz), it can be driven by 6N 137.
TLP52 1 can be used for driving if it is lower than 20KHz.
High-speed optical coupler with amplification and shaping, such as 6n137/TLP113/TLP2630/4N25, etc.
