Part Number: DAC904

Hi Team,

Can you give us more information on the output states of DAC904 when it enters power-down mode? The datasheet unfortunately lacks further characterizations. Asking this as our customer has the DAC with an amplifier set-up measuring a +/- 5Vpp in normal operations. This was reduced to +/- 0.5Vpp upon entering power-down mode. is this the expected behavior of the DAC?

Thanks in advance!


Kind Regards,

Jejomar

  Jejomar,

  We are looking into this. Did they measure the +/-0.5Vpp at the DAC output or the amplifier output? 

  Regards,

  Jim

  Hello Jim,
  
  The  +/-0.5Vpp were measured at the amplifier output.

  Jejomar,

  We are seeing 0V at the DAC output when doing this test. Please try to measure this at the DAC output as the issue may be with the amplifier.

  Regards,

  Jim
