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. AV_DD = DV_DD = 4.5 to 5.5 V, AV_CC = 12 V, IOV_VDD = 1.8 to 5.5 V, AGND = DGND = 0 V, AV_EE =
AV_SSB = AV_SSC = AV_SSD = –12 V (for DAC groups in negative range) or 0 V (for DAC groups in positive ranges), DAC output
range = 0 to 10 V for all groups, no load on the DACs, T_A = –40°C to 105°C
