Other Parts Discussed in Thread: TPA3255, TPA3245
Hello,
Our customer try to design LPF of TPA3251 seeing Apps note slaa701a "Table 1. Class-D Filter Types and Their SE Equivalent Circuits" on page 8.
There are LPF configurations as Type-1 for AD mode, Type-2 for BD mode and Hybrid. We know BD mode cannot accept Cbtl which placesd across +output and -output node.
In the case of TPA3251, no description of PWM mode on the datasheet.
We would like to confirm PWM mode of TPA3251 and suitable LPF type.
Our expectation is that its AD mode and all of LPF type can be used. Is it correct?
Regards,
Mochizuki
