Part Number: OPA2333

Hi Team,

 I recently read the article(TI Precision Designs: Verified Design
High-Side Voltage-to-Current (V-I) Converter and have some questions about how to achieve 1M bandwidth.

Several op-amps with higher bandwidth are mentioned in the article, and some design suggestions are also provided.  I tried to replace the op-amp or zero pole compensation, but I couldn't make the bandwidth 1M. Now I am confused, can you give me some directional guidance on the logic to solve the problem or how to design an ideal 1M bandwidth?

   Any help appreciated! Thanks!

  • Hi ,

    Please reload your image. You have to use Insert/Edit Media to upload an image file. 

    OPA2333 does not have the BW of 1MHz. So you need to find an op amp to have the BW with 5-10Mhz range first in order to make this happen (depends on your gain). What is your application? and how much current are your going to convert from V-I?

    Best,
