DAC7634: Output amplitude from +/-5V to +/-10V

Part Number: DAC7634
Other Parts Discussed in Thread: DAC81404

Daer Team,

My customer is looking for a DAC, and their equirements are as follows,
<Requirements>
  - 4ch
  - 16-bit
  - Settling Time < 250us
  - Output ±10V
  - SPI I/F

I chosed the DAC7634, but output of this DAC7634 is +/-5V.
Do you have any suitable application which amplitudes output from +/-5V to +/-10V?

Best Regards,

Koshi Ninomiya

    Koshi-san,


    I think the DAC81404 would be a good device for the customer application. This device has four channels and is 16-bit resolution. The settling time is much faster than 250us. The device has output range settings from ±5 V, ±10 V, and ±20 V in bipolar ranges, and 5 V, 10 V, 20 V, and 40 V in unipolar ranges. The device also works with SPI.

    You can find more details about the DAC81404 in the product folder: https://www.ti.com/product/DAC81404
