They include a 2.
5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.
5 V (gain = 1) or 5 V (gain = 2).
The devices operate from a single 2.
7 V to 5.
5 V supply and are guaranteed monotonic by design.
The AD5672R/AD5676R are available in a 20-lead TSSOP and in a 20-lead LFCSP and incorporate a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remains there until a valid write.
The AD5672R/AD5676R contain a power-down mode, reducing the current consumption to 1 µA typical while in power-down mode.
The AD5676R is also available in a 16-ball WLCSP.
