Product Details

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 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

  1. Octal, 12-/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

  • Process control
  • Data acquisition systems
  • Portable battery-powered instruments

EVAL-AD5629R Circuit Diagram

Product Details

The EVAL-AD5629RSDZ/EVAL-AD5669RSDZ evaluation boards help users quickly prototype new AD5629R/AD5669R circuits and reduce design time. The AD5629R/AD5669R operates from a single 2.7 V to 5.5 V supply. The AD5629R/AD5669R has an internal 1.25 V or 2.5 V reference giving an output voltage span of 2.5 V or 5 V. The internal reference is off at power-up, allowing the use of an external reference; the REF195 is provided on-board as a 5 V reference source. The device must be written to after power-up to turn on the internal reference.


The evaluation boards interface to the USB port of a PC via the SDP-B board. Software is supplied with the evaluation boards to allow the user to program the AD5629R/AD5669R.


The evaluation boards are compatible with the EVAL-SDP-CB1Z Blackfin® SDP controller board (SDP-B), available to order on the Analog Devices website at www.analog.com.


Full data on the AD5629R/AD5669R is available in the corresponding data sheets, available from Analog Devices, which should be consulted in conjunction with UG-867 when using the evaluation boards.
