The AK7835 series are monaural Class-D amplifiers that deliver 1.55W per channel into 8ohm load from a 5V supply. Class-D operation ensures higher efficiency and low power consumption. Filter-free solution enables “space-saving” layout and BOM cost reduction. Since AK7835 uses very low EMI design, it provides simple adoption for RF related applications, such as Mobile Phones, Portable Multimedia Players and Handheld Gaming Consoles. AK7835 is available both 9-pin WLCSP and 10-pin TMSOP packages.
