TDA8948J 4-channel audio amplifier Rev. 01 — 27 February 2008 www.DataSheet4U.com Product data sheet 1. General description 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. The TDA8948J is pin compatible with the TDA8944AJ, TDA8946AJ and TDA8947J. The TDA8948J contains a unique protection circuit that is solely based on multiple temperature measurements inside the chip.
