The TPA321DR from Texas Instruments is a mono audio power amplifier optimized for low-voltage applications requiring internal speakers. It supports a wide power supply range from 2.5V to 5.5V.
This amplifier can deliver up to 350mW of continuous power into an 8-ohm load at 5V supply, with less than 1% THD+N in the voice band. When operating at 3.3V, it provides 250mW into an 8-ohm load. The device also features an ultralow supply current of 0.15 µA in shutdown mode, making it suitable for power-sensitive battery-powered equipment.
The TPA321DR is available in an 8-pin SOIC package and a surface-mount MSOP package, which offers reduced board space and height. Its bridge-tied load (BTL) configuration eliminates the need for external output coupling capacitors in most applications.
Key features include thermal and short-circuit protection, ensuring device reliability. The amplifier is characterized up to 20 kHz but optimized for narrower band applications like cellular communications.
