14W stereo Class AB amplifier for consumer audio
The STMicroelectronics TDA7269A is a Class AB stereo audio amplifier delivering 14W per channel into an 8Ω load from a split supply rail of ±5V to ±20V. It integrates depop, mute, short-circuit and thermal protection, and standby features, reducing the external component count around the amplifier stage. The through-hole Multiwatt-11 package (vertical, bent and staggered leads) suits PCB layouts where a heatsink is attached directly to the package back — common in powered speakers, AV receivers, and compact stereo amplifiers.
Package and thermal — heatsink planning
The Multiwatt-11 through-hole package has a metal tab on the back that must be bolted to a heatsink for any continuous output above a few watts. The vertical, bent and staggered lead form fits a standard 11-pin staggered footprint — verify the hole pattern and lead spacing against your PCB layout before committing the board. Thermal compound between the tab and heatsink is standard practice; the package is not isolated, so the tab is at the negative supply rail potential and the heatsink must be electrically floating or grounded accordingly.
The ROHS3 rating covers all six original restricted substances plus the four phthalates — no exemption declarations needed for EU-market shipments.
