6.9 Electrical Characteristics

minimum and maximum specifications apply from TA = –40°C to +125°C (for AMC1301S: TA = –55°C to +125°C), VDD1 =

3.0 V to 5.5 V, VDD2 = 3.0 V to 5.5 V, INP = –250 mV to +250 mV, and INN = GND1; typical specifications are at TA = 25°C,

VDD1 = 5 V, and VDD2 = 3.3 V (unless otherwise noted)
