SBAS792A – APRIL 2017 – REVISED APRIL 2017
Electrical Characteristics (continued)
Minimum and maximum specifications apply from T_A = –40°C to +125°C, VDD1 = 3.0 V to 5.5 V, VDD2 = 3.0 V to 5.5 V,
VINP = –250 mV to +250 mV, and VINN = 0 V. Typical specifications are at T_A = 25°C, VDD1 = 5 V, and VDD2 = 3.3 V
(unless otherwise noted).
