TDF8599
I2C-bus controlled dual channel class-D power amplier
In non-I2C-bus mode, pin MOD is used to select:
1. AD or BD modulation (see Section 8.4.1).
2. 1
2 π phase shift when an oscillator is used in Slave mode (see Section 8.4.2).
3. Parallel mode operation (see Section 8.4.3).
In I2C-bus mode, pin MOD can only select Parallel mode. In addition, the modulation
mode and phase shift are programmed using I2C-bus commands.
[1]
See Section 8.4.3 on page 14 for more detailed information.
The information on pin MOD is latched when one of the TDF8599 outputs starts switching,
to avoid incorrect information on pin MOD caused by disturbances of switching amplier
outputs.
8.4.1 Modulation mode
In non-I2C-bus mode, pin MOD is used to select either AD or BD modulation mode (see
Table 8). In I2C-bus mode, the modulation mode is selected using an I2C-bus command.
AD modulation mode: the bridge halves switch in opposite phase.
BD modulation mode: the bridge halves switch in phase but the input signal for the
modulators is inverted.
Figure 10 and Figure 11 show simplied representations of AD and BD modulation.
