The Texas Instruments TPA3144D2 is an efficient Class-D audio power amplifier capable of driving bridged-tied stereo speakers. It delivers up to 6W per channel into 4-Ω, 6-Ω, or 8-Ω loads, depending on the supply voltage, which can range from 4.5V to 14.4V.
This amplifier features advanced EMI suppression technology, enabling the use of inexpensive ferrite bead filters. It boasts up to 90% efficiency, eliminating the need for heatsinks. Key electrical characteristics include low output noise (<65 µV A-wgt) and low THD+N (<0.05% at 1 W/4 Ω/1 kHz).
The TPA3144D2 includes robust SpeakerGuard™ speaker protection circuitry, which incorporates Automatic Gain Limit, an adjustable power limiter, and DC protection. It also offers protection against pin-to-pin, pin-to-ground, and pin-to-power shorts, as well as thermal protection, with auto-recovery features.
Packaged in an HTSSOP (PWP) with dimensions of 9.7 mm × 6.4 mm, this device is suitable for various consumer audio applications such as televisions, BT speakers, wireless speakers, and USB speakers.
