HWD2182
250mW Audio Power Amplifier with Shutdown Mode
General Description
Key Specifications
The HWD2182 is a single-ended audio power amplifier ca-
pable of delivering 250mW of continuous average power into
an 8Ω load with 1% THD+N from 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.

table systems.
