The TFA9812 is a high-efﬁciency Bridge Tied Load (BTL) stereo Class-D audio ampliﬁer with a digital I2S audio input.

digital sound processing and audio power ampliﬁcation. It supports I2C control mode and Legacy mode. In Legacy mode I2C involvement is not needed because the key features are controlled by hardware pin connections. A continuous time output power of 2 × 12 W (RL = 8 Ω, VDDP = 15 V) is supported without an external heat sink. Due to the implementation of a programmable thermal foldback even for high supply voltages, higher ambient temperatures, and/or lower load impedances, the device operates wit.
