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 ideal for portable applications that require small footprints.
