DA7202 8 W Mono Class-D Amplifier for 2S Battery Devices General Description The DA7202 is a powerful, high-efficiency, low-EMI Class-D speaker driver that can drive 8 W into 4 Ω loads directly from a 2S lithium-ion battery pack. The DA7202 is a standalone high performance mono Class-D audio amplifier targeted at powering a variety of two cell portable 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 sound louder on portable devices. The DA7202 can be directly connected between the two-cell battery and the speaker.
