Class D mono amplifier in PowerSSO-36 — 100 W into 6 Ω
Built-in short-circuit and thermal protection, plus mute and standby pins, reduce external BOM count. The -40°C to 85°C ambient rating covers outdoor telecom shelters, automotive cabin installations, and factory-floor audio zones — places where the 0°C to 70°C TDA7498ETR would not qualify. Packaged in a 36-lead PowerSSO-36 EPU with an exposed pad for heat sinking. The mono output and single supply simplify PCB layout compared to a stereo bridge-tied-load design; one decoupling cap per rail and the output filter inductor are the main passives needed.
Sourcing and verification notes
Supplied through independent distribution channels. Each reel is verified for date-code consistency and marking legibility — the PowerSSO-36 EPU package laser etch should match ST's plant-specific font. Counterfeit risk on a current-production audio amp is low, but a mismatched date-code lot or sanded top surface would flag a suspect reel.
