The Texas Instruments TPA751DR is a 700-mW, mono, analog input, Class-AB audio amplifier designed for low-voltage applications. It is optimized for narrower band applications such as wireless communications and is suitable for devices requiring internal speakers.
This amplifier operates with a wide power supply compatibility ranging from 2.5 V to 5.5 V. At a 5V supply and an 8-ohm load, it can deliver 700mW of output power with a typical THD+N of 0.5% at 1 kHz. When operating with a 3.3V supply, it provides 250mW into an 8-ohm load.
The TPA751DR features a bridge-tied load (BTL) configuration, which eliminates the need for external output coupling capacitors in most applications, making it ideal for small, battery-powered equipment. It also includes thermal and short-circuit protection. The device is available in surface-mount packaging such as HVSSOP and SOIC.
Its operating temperature range is from -40°C to 85°C. The amplifier exhibits high power supply rejection at 217 Hz, with 84 dB at 5V and 81 dB at 3.3V. In shutdown mode, it consumes an ultralow supply current of 1.5 nA.
