GENERAL DESCRIPTION
Key Specifications audio power amplifiers are designed specifically to provide n All other HWD2171 packages: 8Ω loa 1.5W (typ) n Shutdown current 0.6µA (typ) n Supply voltage range 2.0V to 5.5V n THD at 1kHz at 1W continuous average output power into 8Ω 0.5% (max) high power, high fidelity audio output. Since the HWD2171 does not require n No output coupling capacitors, bootstrap capacitors, or output coupling capacitors, bootstrap capacitors, or snubber snubber circuits required networks, it is ideally suited for low-power portable systems n Unity-gain stable that require minimum volume and weight. n LLP, MSOP, SO, or DIP packaging Additional HWD2171 features include thermal shutdown pro- n External gain configuration capability tection, unity-gain stability, and external gain set. n Pin compatible with the HWD2161 Note 1: An HWD2171LD that has been properly mounted to a circuit board will Applicationsdeliver 3W into 3Ω (at 10% THD). The other package options for the HWD2171 will deliver 1.5W into 8Ω (at 10% THD).
