description  
The TPA311 is a bridge-tied load (BTL) or  
single-ended (SE) audio power amplifier devel-  
oped especially for low-voltage applications  
where internal speakers and external earphone  
operation are required. Operating with a 3.3-V  
supply, the TPA311 can deliver 250-mW of

continuous power into a BTL 8-Ω 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. A unique  
feature of the TPA311 is that it allows the amplifier to switch from BTL to SE on the fly when an earphone drive  
is required. This eliminates complicated mechanical switching or auxiliary devices just to drive the external load.  
This device features a shutdown mode for power-sensitive applications with special depop circuitry to virtually  
eliminate speaker noise when exiting shutdown mode and during power cycling. The TPA311 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%.
