I can see that the TI A/D PCM1808-Q1 will operate to 125'C, we are always going to struggle to get to 150'C. But, given that i was advised that the TAS6421 had better thermal performance i did not expect to be presented with another major stubling block…
Hirotaka san,
<Q1> Do you mean the TPA3118D2EVM ?
The FAULTZ pin reports to some general fault like Over-temp, DC Detect, Open drain..
( High level for normal operation, and Low for fault condition) if you short the JP3 whenever there is any fault…
Hello Kiran,
The best reference design we can give you is the device's evaluation module. In TPA3118D2EVM's User's guide you can find the schematic and brief description of how to operate the amplifier.
Also, for layout reference, you can find the…
Hi, Mickey
It seems customer's schematic has some mistakes.
Why they use 10nF and 1kohm resistor to act as a High pass filter in TPA3130D2's input, could you confirm with customer if they have a Low pass filter between the Codec's output and TPA3130D2…
Other Parts Discussed in Thread: TPA3118D2 , TPA3118D2EVM We used 2 TDA3118D2 ICs to design a 2.1 speaker system. We did some EMI pre-scan and found serious conducted EMI issues. When we put both TPA3118D2 ICs in shut-down mode, these conducted EMI noises…
