As we know, TDA7498E is designed for Audio amplifier application.  But we are interested in using it for DC amplifier application.

In our application, an inductance coil is connected to amplifier output. This load is up to 24VDC / 3A max, so Class D amplifier is idea for it.

But the operating frequency range is from 0Hz-100Hz, which is different with Audio application. Can we just remove the DC-block capacitor from the input circuit, and use TDA7498E in this DC amplifier application?

Why there is no reply since 5 days ago? Is this forum alive?

Areas of the forum are alive, but are always dependent on participation.

Review with other engineers at you own company, and perhaps prototype/experiment.
