General Description
The APA0710 is a bridged-tied load (BTL) or singled-
ended (SE) audio power amplifier developed especially
for low-voltage applications where internal speakers
and external earphone operation are required. The
APA0711 is a only BTL audio power amplifier developed
especially for low-voltage applications where internal
speakers are required. Operating with a 5V supply,
the APA0710/1 can deliver 1.1W of continuous power
into a BTL 8Ω load at 10% THD+N throughout voice
band frequencies. Although this device is characterized
out to 20kHz,its operation is optimized for narrow 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 APA0710 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 APA0710/1 are available
in an 8-pin SOP and 8-pin MSOP-P with enhanced
thermal pad.
