description  
The TPA701 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 TPA701 can deliver 250-mW of  
continuous power into a BTL 8-Ω load at less than 0.6% 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  
wireless 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 supply current of 1.5 nA during shutdown.  
The TPA701 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%.
