NXP Semiconductors TDA8948J

The TDA8948J contains four identical audio power ampliﬁers. The TDA8948J can be used as four Single-Ended (SE) channels with a ﬁxed gain of 26 dB, two times Bridge-Tied Load (BTL) channels with a ﬁxed gain of 32 dB or two times SE channels (26 dB gain) plus one BTL channel (32 dB gain) operating as a 2.1 system. The TDA8948J comes in a 17-pin Dil-Bent-Sil (DBS) power package.
