GENERAL DESCRIPTION The AD5629R/AD5669R devices are low power, octal, 12-/16- The parts incorporate a power-on reset circuit to ensure that bit, buffered voltage-output DACs. All devices are guaranteed the DAC output powers up to 0 V (AD5629R-1/AD5629R-2, monotonic by design. AD5669R-1/AD5669R-2) or midscale (AD5629R-3/AD5669R-3) and remains powered up at this level until a valid write takes place. The AD5629R/AD5669R have an on-chip reference with an The part contains a power-down feature that reduces the current internal gain of 2. The AD5629R-1/AD5669R-1 have a 1.25 V, consumption of the device to 400 nA at 5 V and provides software- 5 ppm/C reference, giving a full-scale output range of 2.5 V. selectable output loads while in power-down mode for any or The AD5629R-2/AD5629R-3 and the AD5669R-2/AD5669R-3 all DAC channels. have a 2.5 V 5 ppm/C reference, giving a full-scale output range of 5 V depending on the option selected. Devices with 1.25 V PRODUCT HIGHLIGHTS reference selected operate from a single 2.7 V to 5.5 V supply. 1. Octal, 12-/16-bit DACs. Devices with 2.5 V reference selected operate from 4.5 V to 5.5 V. 2. On-chip 1.25 V/2.5 V, 5 ppm/C reference. The on-chip reference is off at power-up, allowing the use of an 3. Available in 16-lead LFCSP and TSSOP, and 16-ball WLCSP. external reference.
