DA7202
10W Mono Class D amplifier for 2S battery operated
portable devices
DA7202 is a powerful, highly efficient, low EMI, standalone high performance mono Class-D
speaker driver designed to drive 10W into 4Ω loads directly from a 2S lithium-ion battery
pack.
DA7202 targets 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 analogue 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.
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 is also included.
DA7202 is available in 9 bump WL-CSP package, 0.5mm pitch, enabling low cost PCB technology,
ideal for portable applications requiring small footprints.
