AD5669RARUZ-1

The device has a built-in on-chip reference with an internal gain of 2. The AD5669R-1 has a built-in 1.25 V, 5 ppm/°C reference with a full-scale output range of 2.5 V; The AD5669R-2 and AD5669R-3 have a built-in 2.5 V, 5 ppm/°C reference with a full-scale output range of 5 V. When powered on, the on-chip reference is turned off, allowing the use of an external reference. The internal reference voltage is enabled by software write.

The device has a built-in power-on reset circuit that ensures that the DAC output is powered up to 0 V and maintains that level until a valid write operation is performed. In addition, it features independent power-saving features for each channel, reducing the device's power consumption to 400 nA at 5 V in power-saving mode and providing software-selectable output loads.
