10W Mono Class D Amplifier for 2S Battery-Operated Portable Devices

The DA7202 is a powerful, highly efficient, low EMI Class D speaker driver that can drive 10W into 4Ω loads directly from a 2S Lithium-ion battery pack to power a variety of two-cell portable applications such as Ultrabooks and tablets.\n\n?\n\nDA7202 uses a fully-differential switched-mode amplifie ? Supports 4Ω and 8Ω loads\n? Input supply range: 4.5V to 9.0V\n? Prms: 9.0W into 4Ω load at 8.2V, 1% THD+N\n? Prms: 10.2W into 4Ω load at 8.2V, 10% THD+N\n? Prms: 3.8W into 8Ω load at 8.2V, 1% THD+N\n? Prms: 5.0W into 8Ω load at 8.2V, 10% THD+N\n? Efficiency: 85% at Pout = 7.0W ;
