Description
The PAM8603M is a 3W, sterero, Class-D audio amplifier with DC volume control. It offers low THD+N, allowing it to produce highquality 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. The PAM8603M is available in SSOP-24 and SOP-18 packages.
