Hi,
Not sure if this is the right place to ask this question.
I am trying to amplify a 0-1000 Hz sin signal to drive a 8 ohm EM load. Can
a class D handle the job?
I saw all the specs only go down to 20 Hz.
Also, I would like the output to be zero if the input is zero.
Anyboday familier with this subject?
Thanks a lot in advance. | p********e

Class D amp has extended upper frequency limit, but not toward the lower
frequency band.
