DAC8568: Need DAC solutions suggestion!!!!

Part Number: DAC8568
Other Parts Discussed in Thread: DAC81408, DAC8775

Tool/software:

Hi team,

My customer asked for DAC solutions and we need BU's help to suggest suitable solutions.

Below list is their requirement:

1. 6 channels

2. Resolution is 16 bits

3. sample rate is no concern

4.there are 5 different output request:

  • Voltage range between 1V and 5V
  • Voltage range between 0V and 10V
  • Voltage range between -5V and 5V
  • Voltage range between -10V and 10V
  • Current range between 4mA and 20mA

According to customer's request, they hope one device could cover all request. If not, please provide each TI suitable solutions.

Thanks

  • I would recommend 2 offerings.

    DAC81408: This will give you 8 channels, all the voltage ranges, but not the current range.

    DAC8775: This will give you 4 channels and cover all the voltage and current ranges.

    Feel free to reach out to my work email.

  • Sohail,

    Good day. My customer provide new requirement as below table.

    Now Our DAC should support negative output voltage and negative output current.

    Customer just needs cheapest/simplest solution 4CH DAC solution. And below table is their analog input specification.

    Please advise.

    Thanks

  • Hi Paul,

    The DAC8775 should still be the best fit here, though I'll let Sohail make the final comment. He is PME for these devices, please feel free to email him for a more in-depth discussion.

    DAC8775:

    The only thing not supported is the smaller IDAC ranges. 

    Best,
