IR21844s Question

[bl4ckw1d0w]

I want to be sure before ordering more of these for the DWM3640 Class D driver board pulled from a Hifonics. Please see the attached image.

I don't care about cost or alternate packaging. I am unsure which one to order.

Also whats the channel type actually mean? See highlighted in photo.

The ICs are typically interchangeable. The IRS is a later version and made to operate with lower drive voltages. I've used both without problems. That said, if yours were marked (most are defaced), use what came in the amp.

Thanks Perry 🙂

I use the SPBF in the Maxxsonics amps.
