It is capable of being driven with 160m W into 32Ω with a 5V supply. The IC is offered with an externally set gain through external resistors. The external gain setting nodes can also be used to configure filters for set-top box applications. The IC has exceptional THD+N over the full audio bandwidth. An on-chip charge pump inverts the power-supply input, creating a negative rail. The output stage of the amplifier is powered between the positive input supply and the output of the charge pump. The bipolar supplies bias the output about ground, eliminating the need for large, distortion-introducing output coupling capacitors. The IC shutdowns and startups without click-pop noise. The IC is available in a 3mm x 3mm, 16-pin QFN-PP and is specified over the extended -40°C to +85°C temperature range. Headphone Amplifier HT97226是一款差分输入/单端输入、可直接输出 驱动的耳机放大器。5V供电时，器件可为32ohm耳机...
