Absolute maximum rating:
Operating FREY M1 under conditions beyond its absolute maximum ratings may damage

when all other parameters are within their specified operating ranges. Functional operation
and specification compliance under any absolute maximum condition, or after exposure to
any of these conditions, is not guaranteed or implied. Exposure may affect device reliability.
