TPA741DR Description

Short technical summary and product information.

The Texas Instruments TPA741DR is a 700-mW, mono, analog input, Class-AB audio amplifier designed for low-voltage applications. It is optimized for narrower band applications such as wireless communications and features integrated depop circuitry.

 

This amplifier operates with a power supply range of 2.5 V to 5.5 V. At a 5V supply, it can deliver 700mW of continuous power into an 8Ω load with less than 0.5% THD+N at 1 kHz. When operating with a 3.3V supply, it provides 250mW into an 8Ω load.

 

The TPA741DR is available in SOIC and HVSSOP surface-mount packages. It includes thermal and short-circuit protection, and a shutdown mode for power-sensitive applications, drawing only 7 µA during shutdown. The BTL configuration eliminates the need for external coupling capacitors on the output in most applications, making it suitable for small battery-powered equipment.

 

Key electrical characteristics include an analog input type, Class-AB architecture, and hardware control interface. The operating temperature range is -40°C to 85°C.
