LMH6553: Is the slew rate definition differential or single ended?

Andre Bauer

Part Number: LMH6553

Hi!

The data sheet specifies the slew rate (at 4V Step, AV = 1) with 2300 V/μs. Is this value to be interpreted differentially, i.e. do the positive and the negative output pin reach "only" 1150 V/µs each?

hey Andre, yes the 2300V/usec is differential - you should only use an FDA with differential outputs,

More slew rate detail is here,

Hi Michael,

Thank you for the answer!

Of course we use the FDA for differential signals. I needed the maximum slew rate for some calculation and wanted to make sure how the specification is meant. Thanks for the confirmation that it supports 2300V/µS differential and therefore 1150 V/µs "per side".

Best Regards,
Andre
