General description
DA7202 is a powerful, high efficiency, low EMI Class-D speaker driver that can drive 10 W into 4 Ω loads directly from a 2S lithium ion battery pack.
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 8 W into an 8 Ω load, making a speaker sound louder on portable devices.
