Electrical Characteristics (continued)
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)

(3) If all channels are loaded with 15mA simultaneously care must be taken to ensure the thermal conditions for the device are not
exceeded.
(4) Not tested during production. Specified by design.
(5) To be sampled during initial release to ensure compliance; not subject to production testing.
(6) No DAC load to AVSS.
