Reworking this by hand is possible with hot air if you pre-bake the board (MSL level not stated, but DSBGA parts are typically MSL 1 or 2 — check the reel label). The orientation mark is a small dot on the top; without it you cannot tell pin 1 from pin 8 after the part is placed.","metaTitle":"TI LM4879ITP/NOPB Class AB Audio Amp, 1.1W Mono, DSBGA","metaDescription":"Texas Instruments LM4879ITP/NOPB Boomer® Class AB audio amplifier, 1.1W mono output into 8Ω, 2.2-5.5V supply, DSBGA-8 package.
