HWD2108

HWD2108 Audio Power Amplifier Dual 105 mW Headphone Amplifier General Description Key Specifications The HWD2108 is a dual audio power amplifier capable of n THD+N at 1kHz at 105mW continuous average output delivering 105mW per channel of continuous average power power into 16Ω 0.1% (typ) into a 16Ω load with 0.1% (THD+N) from a 5V power supply. n THD+N at 1kHz at 70mW continuous average output audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since power into 32Ω 0.1% (typ) n Output power at 0.1% THD+N at 1kHz into 32Ω 70mW (typ) the HWD2108 does not require bootstrap capacitors or snub- ber networks, it is optimally suited for low-power portable Features systems. n LLP, MSOP, and SOP surface mount packaging The unity-gain stable HWD2108 can be configured by external n Switch on/off click suppression gain-setting resistors. n Excellent power supply ripple rejection n Unity-gain stable n Minimum external components Applications n Headphone Amplifier n Personal Computers n Portable electronic devices Typical Application *Refer to the Application Information Section for information concerning proper selection of the input and output coupling capacitors.
