The TPA731DGN is a 700-mW, mono, analog input Class-AB audio amplifier with differential inputs from Texas Instruments. It is designed for low-voltage applications requiring internal speakers.
This amplifier operates with a wide supply voltage range of 2.5 V to 5.5 V. At a 5V supply, it can deliver 700mW of output power into an 8Ω load with a THD+N of 0.5% at 1 kHz. At a 3.3V supply, it provides 250mW into an 8Ω load. The device features an ultralow supply current of 1.5 nA in shutdown mode, making it suitable for power-sensitive applications.
The TPA731DGN utilizes a bridge-tied load (BTL) configuration, which eliminates the need for external output coupling capacitors in most applications. This is particularly beneficial for small, battery-powered equipment. The amplifier is characterized out to 20 kHz but is optimized for narrower band applications, such as those found in wireless communications.
Available in an 8-pin SOIC package and a surface-mount MSOP package, the TPA731DGN offers flexible integration options. The MSOP package reduces board space by 50% and height by 40% compared to standard SOIC packages. It includes thermal and short-circuit protection.
