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.

I use the SPBF in the Maxxsonics amps.
