Applications

* such as Ultrabooks™ and tablets. It uses a fully-differential switched-mode amplifier architecture with a fixed +18 dB gain, with differential analogue inputs. It also has a PWM modulator and an H-bridged switched power output stage that delivers 5 W (dynamic) into an 8 Ω load, making a speaker soun
