That output level suits dashboard chimes, turn-signal tones, and low-power audio feedback in automotive body modules where a full audio head unit is overkill. The 1.6 W rating is into 8 Ω — derate for lower impedances or higher ambient temperatures per the thermal curve.
The pad also provides a low-inductance ground return for the output stage.
ROHS3 compliant and listed as Active in production.
Yes, the BD78326EFJ-ME2 is part of the Automotive, AEC-Q100 series, qualified for automotive applications.
The closest functional peer is the BD78310EFJ-ME2, also a 1.6 W Class AB monaural amplifier in the same 8-HTSOP-J package and AEC-Q100 grade. The BD78310EFJ-ME2 is a direct alternative for dual-sourcing.
Yes, the BD78326EFJ-ME2 is ROHS3 Compliant.
