THS4509: Suggest a Aerospace Grade equivalent of LTC6406IMS8E#PBF from TI

Hi Shyam,

We have a few fully differential amplifiers that are space rated, I attached a link below that lists all of them. If your bandwidth requirement is in the 3GHz range, I would recommend the LMH5401-SP. If this is a part you are interested in I can forward this thread to the appropriate team to further assist you.

Hi,

My apologies

I have to correct my statement.

I am looking for Avionics Grade which must be suitable for Air Platforms, Not Space Platforms/Programs

Here in my case its DO-254 Compliance, which is widely followed for ASIC/FPGA/ICs.

Kindly educate me here, when your customers chose parts for Avionics grade do they use AEC Qualified parts for adapting reliability,  or will be using special space qualifying ICs ?

Here i am aware that AEC is not a standard for Avionics / space, but people choose for better reliability i assume, so that they can qualify entire board for DO-254 screening.

Hello Shyam,

   Does this mean you do not need the space qualification (-SP, -SEP) which would mean devices that qualify for QML Class B and Class V in accordance with MIL-PRF-38535, links for more information can be found here:

2. https://www.ti.com/lit/ml/slyb235a/slyb235a.pdf?

  Or do you need a high reliability part (-EP) which would be in accordance with GEIA-STD-0002-1

  Or automotive qualified which would be in accordance with AEC-Q100

   TI provides documentation for functional safety that our customers can use in order to support DO-254 certification of their systems.  For Functional Safety Compliant devices, this documentation includes FMEDA, FTA, etc, as can be seen below.  Additional information can be found at Functional safety | TI.com

Thank you,

Sima

Your were right , i wish to follow the MIL-PRF-38535 standard

I wish to see the parts in Opamp/ADC/Regulators qualifying this standard.

Hi Shyam,

That standard will fall under space qualified devices. The best option for that case was the original space grade device I recommended. 

Best Regards,

Ignacio
