[Features]
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 in both 9-pin WLCSP and 10-pin TMSOP packages. Gain is selectable from 4(V/V) or 5(V/V).
