TDA7561

Examples of bytes sequence

1 - Turn-On diagnostic - Write operation

Start

Address byte with D0 = 0

ACK

IB1 with D6 = 1 ACK IB2 ACK STOP

2 - Turn-On diagnostic - Read operation

Start Address byte with D0 = 1 ACK DB1 ACK DB2 ACK DB3 ACK DB4 ACK STOP

The delay from 1 to 2 can be selected by software, starting from T.B.D. ms

3a - Turn-On of the power amplifier with 26dB gain, mute on, diagnostic defeat.

Start

Address byte with D0 = 0

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).

Start Address byte with D0 = 1 ACK DB1 ACK DB2 ACK DB3 ACK DB4 ACK STOP

s 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 leackage current or humidity between pins.

s The delay from 4 to 5 can be selected by software, starting from T.B.D. ms
