I need differential line driver for ARINC 429. Output impedance must be 37.4 OHMS

Hi Ramin,

I am going to send this over to our amps team - they may have a good line driver amplifier for this type of application - I don't think our standard transceiver options are going to meet this need - but we may have some line drivers that can.

Thank you sir,

I use parts from TI for many reasons:

Variety, Price, availability, support , Quality

Hey Ramin,

Going to move this over to the High Speed amplifiers, group. They will have more selection in the way of FDAs. Sorry for the multiple forwards but hopefully they will have something to suit your application.

Jerry

Thank you sir

Hello Ramin,

Our HSAMPs line driver portfolio may be a good fit for your ARINC 429 application.  In addition to the heavy 37.4 Ohm load, are there other circuit or subsystem requirements which are important to the design?  Several of our amplifiers have different minimum power supply voltages, various bandwidths, minimum stable gains, and slew rates.

Does the output impedance need to be within a tight tolerance of 37.4 Ohms?  Is that a differential or series load on the amplifier?

Some amplifiers I would suggest at first glance are THS6222 & OPA2675.

I will read up on ARINC 429 in the interim to better understand the application.

Best,

Alec

Hello Ramin,

Thank you for the update!  If you find you need a more powerful line driver solution in the future, please do not hesitate to ask.

Best,
