The TPA301DGN is a mono, Class-AB audio power amplifier from Texas Instruments, optimized for low-voltage applications requiring internal speakers. It operates with a wide power supply range of 2.5 V to 5.5 V.
This amplifier can deliver 350 mW of continuous power into an 8 Ω load at 5 V with less than 1% THD+N. It is characterized out to 20 kHz but optimized for narrower band applications like cellular communications. The bridge-tied load (BTL) configuration eliminates the need for external output coupling capacitors, which is beneficial for small, battery-powered equipment.
The TPA301DGN features a shutdown mode with an ultra-low quiescent current of 0.15 µA, making it suitable for power-sensitive designs. It also includes thermal and short-circuit protection. The device is available in surface-mount packages, including HVSSOP (DGN) and SOIC (D), with the HVSSOP offering a smaller footprint.
Key electrical specifications include an analog input type, Class-AB input architecture, and hardware control interface. The operating temperature range is -40°C to 85°C.
