Semiconductors\Audio ICs\Audio AmplifiersTPA3138D2 Stereo Class-D Speaker AmplifierTexas Instruments TPA3138D2 Stereo Class-D Speaker Amplifier is a 10W/ch, high-efficiency, low-idle-current Class-D stereo audio amplifier. The amplifier can drive stereo speakers with a load as low as 3.2Ω. The 1SPW mode consumes a low idle current of only 21mA (12V) and can operate down to 3.5V. This feature allows for longer audio play and improved thermal performance in BLUETOOTH® speakers, battery-powered appliances, and other power-sensitive applications. Advanced EMI Suppression with Spread Spectrum Control enables the use of inexpensive ferrite bead filters while meeting EMC requirements for system cost reduction.
