Note) *1:Absolute Maximum Ratings is values which must not be exceeded to guarantee device reliability and life,
and when using a device in excess even a moment, it may immediately cause damage to device or may significantly deteriorate
its reliability
*2: Input terminal means MOD0, MOD1, GAIN0, GAIN1, SCLK, SDIN, LRCLK, and PDN terminal.
