Product details

The STMicroelectronics TDA7266M is a Class AB audio amplifier IC delivering 7W into an 8Ω load from a single mono channel. It operates from a 3V to 18V supply and includes mute, standby, and short-circuit/thermal protection. The through-hole Multiwatt-15 package with staggered leads suits it for single-board audio designs in consumer and commercial equipment — powered speakers, intercoms, small PA systems, and TV audio stages where a compact through-hole footprint with a bolt-down heatsink is preferred.

Rated at 7W continuous into 8Ω, this part drives a single speaker or transducer at moderate volume. That power level fits desktop or portable audio where a stereo pair isn't needed — think a single-channel monitor amp or a voice-alarm driver. The 3V minimum supply lets it run from a 3.3V rail, though full output requires the upper end of the range.

Housed in a Multiwatt-15 with vertical, bent, and staggered leads — a through-hole package that requires a heatsink for thermal management at 7W output. The staggered lead pattern matches standard Multiwatt-15 footprints; verify the hole pattern and heatsink mounting hole alignment before layout.

Frequently asked questions

What is the output power of TDA7266M?

The TDA7266M delivers 7W into an 8Ω load from a single mono channel.

Is there a second source or replacement for TDA7266M?

The closest functional sibling is the TDA7266, which is a stereo (2-channel) version of the same 7W Class AB amplifier in the same Multiwatt-15 package. It is not a direct pin-for-pin replacement — the channel count differs — but it shares the same protection features and supply range. No official replacement has been announced for the mono TDA7266M.
