The TPA3122D2 is a 15-W stereo Class-D audio power amplifier designed for driving single-ended speakers or mono bridge-tied loads. It operates efficiently with a supply voltage range of 10 V to 30 V, delivering 10 W per channel into a 4-,Ѷ load from a 17-V supply and 15 W per channel into an 8-,Ѷ load from a 28-V supply. The amplifier features four selectable fixed gain settings of 20, 26, 32, and 36 dB, allowing for flexibility in audio applications. The device includes an internal oscillator, eliminating the need for external components, and provides thermal and short-circuit protection with an auto-recovery feature. It is packaged in a 20-pin DIP format, making it suitable for various applications, including televisions. The TPA3122D2 is noted for its high efficiency, which can reduce the need for external heat sinks during operation.
