OPA333-Q1: What is the total current consumption when act as a tracking circuit?

Part Number: OPA333-Q1
Other Parts Discussed in Thread: OPA333

Dear team,

What is the total current consumption when act as a tracking circuit as below? Iload plus Iq?

Thanks & Best Regards,

Sherry

  • Hi Sherry,

    Yes, the total current consumption is the addition of the quiescent current plus the load current. 

    The average load current is dependent on the load impedance, and the amplitude and frequency of the signal.

    In order to estimate the load current, you will need to know the impedance characteristics of the load the OPA333 is driving, as well as the amplitude and frequency of the signal.  

    Thank you and Best Regards,
