• alternative to AD8608 op amp for active filter design - ADAU1701

    Hi all, 

    I've been looking to implement an active reconstruction filter on the DAC output of my custom ADAU1701 however the op-amp recommended in the datasheet  seems to be end of life and highly priced at the moment (at least via lcsc). Is anyone able…

  • Adau1701 dac output passive vs active.

    Hi guys,

    I'm not sure which type of adau1701 output I should use (Passive vs Active), what are the advantages of one over the other, not to mention the cost?

    When using AD8608 or another operational amplifier...
       a) Is there any gain in quality?

  • RE: Operational Amplifier for a sensor with picoAmps signal.

    Hi Fyle,

    I found some amplifiers that may interest you. You may check them as a start (see datasheet links below): 
    AD8608 , LTC6087, and LTC6240 .
    You may also want to check this circuit as reference: CN0350 .

    I hope these will help you on your circuit design.

  • RE: DAQ-CN0350 Solution Input Charge


    Your computation for C2 and the system error is correct. The system error arises from multiple sources such as temperature drift of the resistors and voltage reference; and offset drifts from the AD8608.
