Product Details
The AD5669R device is a low power, octal, 16-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 an internal 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-3 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 reference 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 an external reference. The internal reference is enabled via a software 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, 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.
