Rated at 3W x 2 into 3Ω, this part is sized for small speakers in soundbars, portable docks, or industrial annunciators.
Marked as Active in production. Note that the RoHS status is listed as non-compliant, so this variant is not suitable for assemblies requiring RoHS exemption-free compliance. If your BOM needs RoHS, check the lead-free suffix variant (MAX9762ETI+T).
This part is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing — stock and lead time are confirmed at quote time.
It is rated for 3Ω loads, delivering 3W per channel into that impedance. Lower impedances will increase output current and thermal stress; higher impedances (4Ω, 8Ω) will produce less power.
