●
3a - Turn-On of the power amplifier with 26dB 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 delay from 1 to 2 can be selected by software, starting from 1ms
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
