description
NOTE: The shaded terminals are used for thermal
connections to the ground plane.
The TPA751 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 TPA751 can deliver 250-mW of
continuous power into a BTL 8-鈩?load at less than 0.6% THD+N throughout voice band frequencies. Although
this device is characterized out to 20 kHz, its operation is 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 TPA751 is available in a 3.0
脳
3.0 mm MicroStar Junior錚?(BGA), 8-pin SOIC surface-mount package and
a surface-mount PowerPAD錚?MSOP.
