PAM8603M

3W Filterless Stereo Class-D Audio Amplifier with DC Volume Control

Features

General Description

3W Output at 10% THD with a 4Ω Load and

5V Power Supply

Filterless, Low Quiescent Current and Low

EMI

Low THD+N

64-Step DC Volume Control from -75dB to

+24dB

Superior Low Noise

Efficiency up to 89%

Short Circuit Protection

Thermal Shutdown

The PAM8603M is a 3W, sterero, class-D audio

amplifier with DC volume control. It offers low

THD+N, allowing it to produce high-quality sound

reproduction. The new filterless architecture

allows the device to drive the speaker directly,

requiring no low-pass output filters, which saves

the system cost and PCB area.

With the same numbers of external components,

the efficiency of the PAM8603M is much better

than class-AB cousins. It can extend the battery

life thus ideal for portable applications.

Few External Components to Save the

Space and Cost

Pb-Free Package

The PAM8603M is available in SSOP-24 and

SOP-18 packages.
