Examples of bytes sequence
TDA7563B
28/33
Doc ID 12733 Rev 6
9
Examples of bytes sequence
1 - Turn-On diagnostic - write operation
2 - Turn-On diagnostic - read operation
The delay from 1 to 2 can be selected by software, starting from 1ms
3a - Turn-on of the power amplifier with 30dB gain, mute on, diagnostic defeat, CD = 2%
.
3b - Turn-off of the power amplifier
4 - Offset detection procedure enable
5 - Offset detection procedure stop and reading operation (the results are valid only for the
offset detection bits (D2 of the bytes DB1, DB2, DB3, DB4)
.
●
The purpose of this test is to check if a D.C. offset (2V typ.) is present on the outputs,
produced by input capacitor with anomalous leakage current or humidity between pins.
●
The delay from 4 to 5 can be selected by software, starting from 1ms
