Dangerous electrical voltage!
Risk of injury.
Make sure that the 24 V DC input voltage satisfies the requirements of
f
"safe isolation".
If possible, design the system circuit so that the booster amplifier and all coupled

internally/externally required system voltages for
• Logic
• Output stage
• Signal processing
