Operating with a 5V supply, the APA0713 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 n a r r o w b an d ap p l i c a t i o n s s u c h as w i r e l e s s 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 special depop circuitry to eliminate...
