6.7 Electrical Characteristics—General 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 = –5 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 = –40°C to 105°C
