Other Parts Discussed in Thread: TINA-TI, LMH6551
Hello
Please allow me fundamental quiestions.
My Customer intend to LMH6551Q-Q1, and need 3Vrms differential output swing with single supply.
Q1
We see data sheet page 5 following.
" Vs=+/-2.5V ,Vcm=0V : Output voltage swing +/-2.8V(TYP) "
Does it mean +OUT termnal= +1.4V, -OUT termnal =-1.4V ( or +OUT=-1.4V, -OUT= -1.4V)?
Q2
Is Output voltage swing same +/-2.8V(TYP) for V+= 5V, V-=0V, Vcm=2.5V?
If no, Output swing should be approx 1.1V lower than V+, higher than V-?
Q3
Customer need 3Vrms differential output swing with single supply.
3V x sqrt(2)=4.24V
So, 2.12V peak should be necessary.
I think V+ >6.5 V and Vcm=3.3V ( 2.12+1.1V) should be necessary... How do you think?
We don't have TINA-TI .tsc file for LMH6551Q-Q1, but please advise.
Thank you
Best Regards
