GENERAL DESCRIPTION
Key Specifications n THD+N at 1kHz, 350mW continuous average output power into 16Ω 10% (max) n THD+N at 1kHz, 300mW continuous average output power into 8Ω 10% (max) The HWD2119 audio power amplifier is designed specifically n Shutdown Current 0.7µA (typ) to provide high quality output power and minimize PCB area with surface mount packaging and a minimal amount FEATURES
of external components. Since the HWD2119 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable applications. n LLP, SOP, and MSOP surface mount packaging. n Switch on/off click suppression. n Unity-gain stable. The closed loop response of the unity-gain stable HWD2119 n Minimum external components. can be configured using external gain-setting resistors. The device is available in LLP, MSOP, and SO package types to APPLICATIONS
suit various applications. n General purpose audio n Portable electronic devices n Information Appliances (IA) Typical Application FIGURE 1.
