The AD5629R device is a low power, octal, 12-bit, buffered voltage-output DACs. It operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design.The AD5629R/AD5669R have an on-chip reference with aninternal gain of 2. The AD5629R-1/AD5669R-1 have a 1.25 V,5 ppm/°C reference, giving a full-scale output range of 2.5 V.The AD5629R-2/AD5629R-3 and the AD5669R-2/AD5669R-3have a 2.5 V 5 ppm/°C reference, giving a full-scale output rangeof 5 V depending on the option selected. Devices with 1.25 Vreference selected operate from a single 2.7 V to 5.5 V supply.Devices with 2.5 V reference selected operate from 4.5 V to 5.5 V.The on-chip reference is off at power-up, allowing the use of anexternal reference. The internal reference is enabled via asoftware write.The part incorporates a power-on reset circuit that ensures that the DAC output powers up to 0 V and remains powered up at this level until a valid write takes place. The part contains a power-down feature that reduces the current consumption of the device to 400 nA at 5 V and provides software-selectable output loads while in power-down mode for any or all DAC channels.Product Highlights Octal, 12-/16-bit DACs. On-chip 1.25 V/2.5 V, 5 ppm/°C reference. Available in 16-lead LFCSP and TSSOP, and 16-ball WLCSP. Power-on reset to 0 V or midscale. Power-down capability. When powered down, the DAC typically consumes 200 nA at 3 V and 400 nA at 5 V.Applications Process control Data acquisition systems Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources
