DESCRIPTION  
The TPA321 is a bridge-tied load (BTL) audio power amplifier developed especially for low-voltage applications  
where internal speakers are required. Operating with a 3.3-V supply, the TPA321 can deliver 250 mW of  
continuous power into a BTL 8-load at less than 1% THD+N throughout voice band frequencies. Although this  
device is characterized out to 20 kHz, its operation was optimized for narrower band applications such as cellular  
communications. The BTL configuration eliminates the need for external coupling capacitors on the output in  
most applications, which is particularly important for small battery-powered equipment. This device features a  
shutdown mode for power-sensitive applications with a quiescent current of 0.15 µA during shutdown. The  
TPA321 is available in an 8-pin SOIC surface-mount package and the surface-mount PowerPAD™ MSOP, which  
reduces board space by 50% and height by 40%.
