HWD2180 Audio PowerAmplifier Dual 250 mW Audio Power Amplifier with Shutdown Mode
General Description
The HWD2180 is a dual audio power amplifier capable of delivering typically 250mW per channel of continuous average power to an 8Ω load with 0.1% THD+N using a 5V power supply.
audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging.
Since the HWD2180 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.
The HWD2180 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.
The unity-gain stable HWD2180 can be configured by external gain-setting resistors.
