Talking THD has a price, and a negative one!

I didn't know we can express THD in US $

Blind testing against the euro should be the judge of that.

Ha-ha, funny mistake, though it's typical manager_based error. About year ago i've found mistake on the Murata site ( http://www.murata.com/cap/index.html ) "Cross Refarence", yeah it's not so funny like THD=-90$, but i already sent them two letter about it (right product should be present on the right site etc), and still no reactions, it seems Murata really mean the "Refarence".

This weekend I just sent an email to ADI because in one of their new chip data sheets they say: "5V, 250A dual opamp". I told them I thought that 250A was pretty optimistic. Within 10 minutes I had a reply saying they realised they would have a hard time to convince me...

Engineers are just like people.

Hèh hèh, that price is negative. Does that mean you get money from the vendor purchasing such an amp? The smaller the distortion the more money you get?

Not electronics, but strange errors appear everywhere since we allowed computers to mess around.

If you measure +1 dB THD at purchase, you get 90 USD. Your gain is 90 USD*THD[dB]. If you measure a negative value, you should to pay for the chip. The price is an additional charge for the final deal.
