10W Mono ClassD for 2S battery

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.
 
DA7202 uses a fully-differential switched mode amplifier architecture with a fixed +18 dB gain and differential analog inputs. It also has a PWM modulator and an H‑bridged switched power output stage that delivers 3.8 Wrms into an 8 Ω load (10.2W into a 4 Ω load), making a speaker sound louder in portable devices.
