In Page 4,
I think the Vout here should be Vload, or (Vout - Vs/2).
Is that right?
Hi, Vic Wu.
Good day! Based on the formula, Vout is equal to Vload.
If we refer on page 11 of AD8275 of the datasheet, there are two equations of Vout depending on the connection of Vref pins but the general equation for this is :
Vout total = Vout + Vref
where: Vout = Vin x Gain = (Vinp-Vinn) x Gain
Vref = (Vref1+Vref2)/2
Therefore, on page 4 Vout is equal to Vload which is equal to Vin x gain and Vs/2 is the Vref .
For more information on power dissipation, please refer to page 4 of this article http://www.analog.com/static/imported-files/tech_articles/MS-2251.pdf.
Hope this helps.
