TPA301DGN General Description

The TPA301DGN is a powerful audio amplifier designed for low-voltage applications requiring internal speakers. With a supply voltage of 3.3V, this amplifier can output 250mW of continuous power into an 8-ohm load with less than 1% THD+N. Its optimized operation in voice band frequencies makes it an ideal choice for applications like cellular communications. The bridge-tied load configuration eliminates the need for external coupling capacitors in most setups, crucial for compact battery-powered devices. Additionally, the amplifier features a shutdown mode with an ultra-low quiescent current of 0.15µA, perfect for power-sensitive applications. Available in an 8-pin SOIC package and PowerPAD MSOP, the TPA301DGN offers a space-saving solution, reducing board space by 50% and height by 40%
