A power-down feature reduces the current consumption to 400 nanoamps at 5 V (120 nanoamps at 3 V). Each of the eight channels of the DAC can be individually powered-down for flexible and incremental power management. The DACs are pin-compatible, allowing engineers to select the correct resolution without having to redesign the circuit board. Data is entered as a 16-bit word consisting of 1 control bit, 3 address bits, and 12 data bits. The unused LSBs are ignored in the lower resolution parts, so the DACs can also be made software-compatible.
