The Texas Instruments TPA301D is an active, mono, Class-AB audio amplifier. It is specifically designed for low-voltage applications requiring internal speakers. The device operates with a wide power supply range from 2.5 V to 5.5 V.
Key electrical characteristics include an output power of 350 mW into an 8 Ω load at 5 V supply, and 250 mW into an 8 Ω load at 3.3 V supply, both with less than 1% THD+N at 1 kHz. The amplifier features a hardware control interface and analog audio input. Its operation is optimized for narrower band applications, such as cellular communications, though it is characterized out to 20 kHz.
The TPA301D is available in surface-mount packages including HVSSOP (DGN) and SOIC (D). The BTL configuration eliminates the need for external output coupling capacitors, which is beneficial for small, battery-powered equipment. It also includes thermal and short-circuit protection, and an ultra-low quiescent current of 0.15 µA in shutdown mode for power-sensitive applications.
