IRCore350M ±60V 350W 4Ω Audiophile Class-D Amplifier, OPA1656 Buffer

$49.00 USD

Designed to get a premium sounding class-d amplifier while providing a large headroom for dynamic music.

Low dropout, low quiescent ±5V regulator ICs were used on the class-d chip's analog supply. Using a good voltage regulator IC in the analog supply section of IRS2092 directly improves the overall sound.

Uses Infineon OptiMos(TM) 3 for the output mosfets. This newer technology mosfets can produce double the output current at 4 ohms load compared with the original reference design with no performance penalty.

Flat wirewound copper, low loss output inductor is used which improves the THD performance and sound of this amplifier module.

The heatsink mounting is designed such that the mosfets can be easily attached to a wide variety of heatsinks that are available in the market.

Package Includes
1 pc assembled and tested mono module, without main heatsink.
