7.5 Electrical Characteristics

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 = +4.5 to +5.5-V, AVCC = +12-V, AVEE = -12-V, IOVDD = +1.8 to +5.5-V, AGND =

DGND = 0-V, AVSSA,B,C,D = 0-V (DAC groups in positive ranges) or -12-V (DAC groups in negative range), DAC output range

= 0 to 10-V for all groups, no load on the DACs, TA = -40°C to +105°C (unless otherwise noted)
