TPA301DR Description

Short technical summary and product information.

The Texas Instruments TPA301DR is a 350-mW mono Class-AB audio power amplifier designed for low-voltage applications requiring internal speakers. It operates with a wide power supply compatibility range of 2.5 V to 5.5 V.

 

This amplifier delivers 350 mW of output power into an 8 Ω load at 5 V supply with less than 1% THD+N. It is characterized out to 20 kHz but optimized for narrower band applications like cellular communications. The BTL configuration eliminates the need for external output coupling capacitors, which is beneficial for small battery-powered devices.

 

Key electrical characteristics include an analog input type, Class-AB architecture, and hardware control interface. The device features thermal and short-circuit protection. It is available in surface-mount packages such as SOIC and MSOP PowerPAD, reducing board space.

 

The TPA301DR also includes an ultra-low quiescent current of 0.15 µA in shutdown mode, making it suitable for power-sensitive applications. Its operating temperature range is -40°C to 85°C.
