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