description
The TPA711 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 TPA711 can deliver 250-mW of continuous power into a BTL 8-
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. A unique feature of the TPA711 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 eliminate speaker noise when exiting shutdown
mode. The TPA711 is available in an 8-pin SOIC and the surface-mount PowerPAD MSOP package, which
reduces board space by 50% and height by 40%.
