LMV722 Output swing

Other Parts Discussed in Thread: LMV722

Hi,

Does anyone have the data of LMV722 output voltage Swing for the condition below,

VCC+=5V, VCC-=GND, RL=1KΩ to VCC+/2, full temp range

We'd like to know the amximum voltage for VOL.

Thanks

Go,

The data sheet has 600 ohm and 2k data.
1k can be interpolated.
2kohm is [1.25mA,135mV], 600 ohm is [4.17mA,215mv], and 1k is [2.5mA,X].

x = 135mV + (215mV-135mV)*(2.5mA-1.25mA)/(4.17mA-1.25mA) = 169mV

169mV is maximum VOL because sinking current chart on page 6 looks linear between 1.2mA and 4.2mA

Hi, Ron

Thank you for your support.

Let me ask you one more thing.

If the load(RL) is placed between LMV722 output and GND,

I think that the minimun VOH value and maximum VOL value will become lower, is it right?

Thanks,

Go,

Yes that is correct.
