The TPA751DGNRG4 is a bridge-tied load (BTL) audio power amplifier designed for low-voltage applications, particularly suitable for internal speaker use. It operates with a supply voltage range of 2.5 V to 5.5 V, providing 250 mW of continuous output power at 3.3 V and 700 mW at 5 V into an 8-ohm load, with total harmonic distortion plus noise (THD+N) below 0.6% across voice band frequencies. The device features a low supply current of 1.5 nA in shutdown mode, making it ideal for power-sensitive applications. It includes thermal and short-circuit protection, ensuring reliable operation. The TPA751 is available in multiple surface-mount packages, including MicroStar Junior (BGA), SOIC, and PowerPAD MSOP, facilitating integration into compact designs.
