The TPA3008D2 is a 10-W (per channel) efficient class-D audio amplifier for driving bridged-tied stereo speakers. The TPA3008D2 can drive stereo speakers as low as 8 Ω. The high efficiency of the TPA3008D2 eliminates the need for external heatsinks when playing music. The gain of the amplifier is controlled by two gain select pins. The gain selections are 15.3, 21.2, 27.2, and 31.8 dB. The outputs are fully protected against shorts to GND, VCC, and output-to-out
The TPA3008D2 is a 10‑W per‑channel, 10‑W stereo Class‑D audio power amplifier designed for driving bridged‑tied stereo speakers. It operates from a single 8.5 V to 18 V supply, eliminates the need for external heatsinks, and offers four selectable fixed gain settings (15.3, 21.2, 27.2, 31.8 dB). The device includes thermal and short‑circuit protection with auto‑recovery.
The datasheet details absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, pin‑out functions, typical performance graphs, and PCB layout recommendations for the PowerPAD™ package. Key performance figures include up to 92 % efficiency, THD+N as low as 0.13 % at 1 kHz, and a signal‑to‑noise ratio of 97 dB.
