Without a proper thermal land, the device will hit its thermal shutdown threshold well before reaching the rated output power. ## Industrial temp range and feature set The industrial temperature grade means the amplifier's bias and output offset stay within spec across the full range. The integrated feature set includes depop circuitry to suppress turn-on clicks, differential inputs for noise rejection, an I²C control interface for volume and mute, an input multiplexer to select between multiple audio sources, and a shutdown pin to drop quiescent current when the amplifier is idle. The mute function lets the output stage stay biased while the audio path is gated — useful for sequenced power-up in multi-amplifier systems.","metaTitle":"TPA0172PWP Texas Instruments Class AB Audio Amp","metaDescription":"Texas Instruments TPA0172PWP Class AB stereo audio amplifier, 2W x 2 @ 4Ohm, 24-HTSSOP, active, ROHS3.
