HWD2119 Audio Power Amplifier
350mW Audio Power Amplifier with Shutdown Mode
General Description
Key Specifications
The HWD2119 is a mono bridged power amplifier that is ca-
pable of delivering 350mWRMS output power into a 16load
or 300mWRMS output power into an 8load with 10%
THD+N from a 5V power supply.
n THD+N at 1kHz, 350mW continuous average output

of external components. Since the HWD2119 does not
require output coupling capacitors, bootstrap capacitors or
snubber networks, it is optimally suited for low-power por-
table applications.
