Audio Power Amplifier

HWD2119

350mW Audio Power Amplifier with Shutdown Mode

General Description

Key Specifications

n THD+N at 1kHz, 350mW continuous average output

The HWD2119 is a mono bridged power amplifier that is ca-

pable of delivering 350mW_RMSoutput power into a 16Ω load

or 300mW_RMSoutput power into an 8Ω load with 10%

THD+N from a 5V power supply.

The HWD2119 audio power amplifier is designed specifically

to provide high quality output power and minimize PCB

area with surface mount packaging and a minimal amount

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.

Features

n LLP, SOP, and MSOP surface mount packaging.

n Switch on/off click suppression.

n Unity-gain stable.

n Minimum external components.

The closed loop response of the unity-gain stable HWD2119

can be configured using external gain-setting resistors. The

device is available in LLP, MSOP, and SO package types to

suit various applications.

Applications

n General purpose audio

n Portable electronic devices

n Information Appliances (IA)
