Part Number: ADS4149

Hi team,

My customer is evaluating  ADS4149.

He is trying to set test patterns(output digital ramp) via SPI using FPGA(3.3V) but it doesn't succeed.

Could you provide any advice to solve this problem?

Setting Sequence:

  1. 0002h Software Reset
  2. 2504 Output Digital Ramp

Other pins setting

  • PIN30 Reset Low
  • PIN7 OE High
  • PIN6 DFS Low

I look forward to hearing back from you.

Best regards,

Shota Mago
