LMH5401: question on Rf = 1k and Rf = 2k

Bob Kolbet

Part Number: LMH5401

Hello

Please let let me know if the LMH5401 has been characterized for Rf = 1K or 2K.

What will be the 3db bandwidth at G =1 and or g = 5?

Will a compensating Cf need to be added?

Hello

I am looking for something similar to the frequency Response vs closed loop gain presented on page 7 of the LTC6409 data sheet.

Sorry - what will be the 3db bandwidth for G =2, ..

Hi Bob,

Figure 1, 2 Shows the 3dB bandwidth for G=2. Device is characterized with below Gain setting resistors:

You can use the TINA model available to simulate for different load capacitances.

Hruday
