TPA3221 – 2 x 100W Stereo 200W Mono Class-D Amplifier

With the TPA3221, Texas Instruments brings out a descendant of the Akita family (TPA3251 TPA3255), which integrates preamp and analog voltage generation. It is therefore suitable to replace the previous long runners TPA3118 as well as TPA3116 .

Other future members of this family (Boxster) are TPA3220, TPA3223, and TPA3225 TPA3227. (TI roadmap CES NAMM 2017),,de,Tp3220,,hi,TPA3223,,ar,TPA3225,,ar,TPA327 TPA32XX,,mt
