Application of voltage in excess of absolute maximum rating or use out absoluted maximum rated temperature environment may cause deterioration of characteristics. (*1) The voltage difference between inverting input and non-inverting input is the differential input voltage. Then input terminal voltage is set to more then VEE. ● Electrical characteristics ○ BU7251 family, BU7252 family (Unless otherwise specified VDD=+3[V], VSS=0[V], Ta=25[℃]) Guaranteed Limit BU7251G BU7251SG BU7252 F/FVM BU7252S F/FVM Parameter Symbol Temperature range Min.
