TDA2822M – STMicroelectronics

The TDA2822M, manufactured by STMicroelectronics, is a monolithic integrated circuit intended for use as a dual low-voltage power amplifier, primarily in portable audio applications. Operating from a supply voltage range of 1.8V to 15V, it can deliver up to 1W per channel into an 8Ω load in stereo configuration, or 2.2W into a 4Ω load in bridge-tied load (BTL) mono configuration. The device features low quiescent current consumption, typically 6mA, and is internally protected against short-circuit conditions and thermal overload. The “50 x 2009 rohs” marking indicates a production date within the 50th week of 2009 and compliance with the Restriction of Hazardous Substances Directive. The “71 x 2004 dc” marking likely represents internal manufacturing traceability codes, potentially indicating a diffusion code and year of manufacture. The TDA2822M is typically available in a DIP-8 or SO-8 package.
