The STMicroelectronics TDA7295 is a Class AB mono audio amplifier IC delivering 80W into an 8Ω load from a ±10V to 40V dual supply. It packs depop, mute, standby, and short-circuit plus thermal protection into a through-hole Multiwatt-15 package — the kind of part you can swap in the field with a screwdriver and a bit of thermal paste. Typical applications include active speakers, subwoofer modules, and PA amplifier repairs where a single-channel high-power stage is needed.
80W continuous into 8Ω drives a single 8Ω speaker. The ±10V to 40V supply range covers indoor consumer and pro-audio gear.
Through-hole Multiwatt-15 — field-service friendly
The Multiwatt-15 package with vertical bent and staggered leads is a through-hole part. That means you can socket it or solder it with a standard iron — no hot-air station needed. The staggered lead pitch helps with PCB layout for high-current traces. Mount it to a heatsink with the tab; the thermal protection will save it if the heatsink is undersized, but don't count on that in production — size the sink for 80W dissipation.
