Other Parts Discussed in Thread: THS4302, LMH5401

Hi,

My customer is using the THS4302, however they need to decrease noise.

Requested condition are following;

- Total Input Referred Noise: Lower 2.8 nV/√Hz

- Current Feed back is NG.

- Band-Width is higher than 1.5GHz

- Single-end output

We would like to suggest LMH5401, though it is differential output.

Is there how to evaluate the LMH5401 correctly with single-end output on EVM ?

Or please let me know if you have good idea to correspond above request.

Best Regards,

Kuramochi

Hello,

Please see this article on from one of our applications engineers on using single-ended outputs of fully-differential amplifiers. I don't believe we have an alternative to the THS4302 in terms of achieving 1.5GHz of BW in a gain of 5V/V. What is the customer end-application?

Samir-san,

Thank you for your information.

Application is a mass spectrometer.
