6.13 Electrical Characteristics

minimum and maximum specifications apply from TA = –40°C to +125°C, VDD1 = 3.0V to 5.5V, VDD2 = 3.0V to 5.5V, VREFIN

= 3.3V, VINP = –50mV to +50mV, and VINN = 0V; typical specifications are at TA = 25°C, VDD1 = 5V, VDD2 = 3.3V, and VREFIN

= 1.65V (unless otherwise noted)
