IDD Current flowing into VDD(3) Normal operation, DAC at midscale 172 µA
Use the device in the minimum current range to meet the electrical specifications.
These devices do not have automatic thermal shutdown. The external circuitry must maintain the junction temperature within the specified limits.
The current flowing into VDD does not account for the load current sourced or sinked on the IOUT pins.
