Other Parts Discussed in Thread: TPA3144D2,
Dear Sirs,
My customer asked us about "Quiescent supply current in shutdown mode" for TPA3140D2,TPA3144D2.
They used TPA 3144 D 2, but since there is no EVM, TPA 3140 D 2 EVM was confirmed in parallel.
As a result, both data sheets
Icc (sd): 40 μA (Typ.) (Max: 60 μA)
On the other hand, when they measure with TPA 3140 D 2 EVM
Icc (sd) = 380 μA
With their board TPA 3144 D2
Icc (sd) = 200 μA
It is 10 times the value of the data sheet.
So I also checked with TPA 3140 D 2 EVM
Icc (sd) = 381 μA
For the confirmation method with EVM, only the power supply is connected (12 V), and the current is measured by pushing the shutdown button.
Is this value correct?
Is there a setting method to be the value of the data sheet?
Please tell me about the above.
Best Regards,
Y.Hasebe
