The TPA721DGN is a mono, Class-AB audio power amplifier from Texas Instruments, specifically developed 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 output power into an 8 Ω load when operating at 5 V, and 250 mW at 3.3 V. It features an analog input and a hardware control interface. The device is characterized for operation up to 20 kHz, with optimization for narrower band applications like wireless communications.
The TPA721DGN includes integrated depop circuitry and thermal/short-circuit protection. Its bridge-tied load (BTL) configuration eliminates the need for external output coupling capacitors in many applications, which is beneficial for small, battery-powered equipment. A shutdown mode is available for power-sensitive applications, drawing only 7 µA during shutdown.
Available in SOIC (D) and HVSSOP (DGN) surface-mount packages, the TPA721DGN offers compact solutions for space-constrained designs. The HVSSOP package, in particular, reduces board space by 50% and height by 40% compared to standard SOIC packages.
The TPA721DGN can deliver 700 mW into an 8 Ω load at 5 V, and 250 mW into an 8 Ω load at 3.3 V.
The TPA721DGN operates with an analog supply voltage between 2.5 V and 5.5 V.
The total harmonic distortion plus noise (THD + N) at 1 kHz is 0.5 %.
The TPA721DGN is available in SOIC (D) and HVSSOP (DGN) surface-mount packages.
The operating temperature range for the TPA721DGN is from -40°C to 85°C.
