The TPA721DGNRG4 from Texas Instruments is a bridge-tied load (BTL) audio power amplifier specifically developed for low-voltage applications requiring internal speakers. It operates with a wide power supply range from 2.5V to 5.5V.
This amplifier can deliver 700mW of continuous power into an 8-ohm load when operating with a 5V supply, and 250mW at 3.3V, both with less than 0.6% THD+N. The BTL configuration eliminates the need for external output coupling capacitors in many applications, making it suitable for small, battery-powered equipment. It also features a shutdown mode with a low supply current of 7µA for power-sensitive applications.
The TPA721DGNRG4 is available in an 8-pin SOIC surface-mount package and a PowerPAD MSOP package, offering space and height reduction. It is fully specified for 3.3V and 5V operation and includes integrated depop circuitry and thermal/short-circuit protection.
This device is characterized out to 20kHz but optimized for narrower band applications such as wireless communications. The operating temperature range is -40°C to 85°C.
