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 au...
