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 AD5669R has an on-chip reference with an internal gain of 2. The user can select the AD5669R with a 1.25 V 5 ppm/°C reference (AD5669R-1), giving a full-scale output range of 2.5 V, or a 2.5 V 5 ppm/°C reference (AD5669R-2 and AD5669R-3), giving a full-scale output range of 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
  1. Octal, 16-bit DACs.
  2. On-chip 1.25 V/2.5 V, 5 ppm/°C reference.
  3. Available in 16-lead LFCSP and TSSOP, and 16-ball WLCSP.
  4. Power-on reset to 0 V or midscale.
  5. Power-down capability. When powered down, the DAC typically consumes 200 nA at 3 V and 400 nA at 5 V.

Applications

  • Optical transceivers
  • Power Amplifier control
  • Data acquisition systems
  • Digital gain and offset adjustment

I appreciated the product, yet I was looking for a different packaging, because my research project is still made with classical PCB components. I understand that there can be technical nd physical reasons to produce only SMD packaging for this kind of (high) precision devices, yet I had my hard time in installing the device ( I used an adaptor). I noticed that the market is generally almost lacking DIP devices over 10bit precision. The device seems to behave very well, anyway.

many bits and less package choices
