6.7 Electrical CharacteristicsâGeneral Specifications
The electrical ratings specified in this section apply to all specifications in this document, unless otherwise noted. These
specifications are interpreted as conditions that do not degrade the device parametric or functional specifications for the life of
the product containing it. AVDD = DVDD = 5 V, AVCC = 5 V, AVSS = â5 V, IOVDD = 1.8 to 3.3 V, PAVDD = 5 V, AGND = DGND =
0 V, external 2.5 V reference, DAC output range = 0 to 5 V for all DACs, no load on the DACs, current sense inputs common
mode at 48 V, TA = â40°C to 105°C
