The APA0710 is a bridged-tied load (BTL) or singledended (SE) audio power amplifier developed especially for low-voltage applications where internal speakers and external earphone operation are required. The APA0711 is an 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. An 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.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
