DA7202

DA7202 10 W Mono Class-D Amplifier for 2S Battery Devices Company confidential 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. The DA7202 can be directly connected between the two-cell battery and the speaker. Noise suppression circuitry to reduce audible pops and clicks at the speaker output is also included. Available as a 9-bump WL-CSP package with 0.5 mm pitch that is suited to low cost PCB technology, it is id...
