TDA1566

I2C-bus controlled dual channel/single channel ampliﬁer

6.1.3 Balanced and unbalanced input sources

The TDA1566 accepts balanced as well as unbalanced input signals. Table 7 and Table 8

show the required hard or software setting and Figure 6 shows the input source

connection. Note that the unbalanced input source should be connected to the positive

BTL channel input. Note that the J version accepts in non-I2C-bus mode only a balanced

input source.

6.1.4 Single channel 1

Ω operation

The input and output pins for single channel 1

Ω operation are listed in Table 9. The 1 Ω

operation requires that on the PCB the output pins are shorted as indicated in Table 9. In

the 1

Ω operation the input signal is taken from channel 1.

To prevent instability in 1

Ω operation the ampliﬁer must not be used in line driver mode

with a load larger than 25

Ω.
