The TPA741DGN is a mono, Class-AB audio power amplifier from Texas Instruments, specifically designed for low-voltage applications requiring internal speakers. It operates with a wide power supply range from 2.5 V to 5.5 V.
This amplifier can deliver up to 700 mW of continuous power into an 8-ohm load when operating at 5 V, and 250 mW at 3.3 V, with a typical THD+N of 0.5% at 1 kHz. The input type is analog, and it features a hardware control interface. The device is characterized up to 20 kHz but is optimized for narrower band applications, such as those found in wireless communications.
Key features include integrated depop circuitry, thermal protection, and short-circuit protection. The BTL (bridge-tied load) configuration eliminates the need for external output coupling capacitors in many applications, which is beneficial for small, battery-powered equipment. The TPA741DGN is available in SOIC and HVSSOP surface-mount packages.
It is suitable for applications requiring a compact audio amplification solution. The device also includes a shutdown mode for power-sensitive applications, drawing only 7 µA during shutdown.
