Class-D Audio Amplifier from Diodes Incorporated Reduces Component Count

PLANO, Texas — (BUSINESS WIRE) — February 12, 2014 — Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced the PAM8407 Class-D audio amplifier. This product integrates an advanced 32-step up/down volume control and enables a reduction in component count in a variety of stereo speaker applications, including PCs, docking stations and wireless speakers.

Able to drive dual 4Ω speakers at 3W per channel from a 5V supply, the amplifier provides designers with simple two key up/down volume control and high-quality sound reproduction. With its fully differential inputs, the device ensures low noise, high PSRR and solid THD+N performance.

The Class-D amplifier’s filter-less output architecture saves space by minimizing the number of external components, while also ensuring a lower quiescent current and improved EMI performance.

With its low pin count SO-16 packaging, small external circuit requirement and an efficiency of 87%, the PAM8407 is particularly appropriate for portable applications. The wide operating voltage range of 2.5V and 6V makes it especially well-suited for a 4x alkaline cell configuration.

The amplifier also incorporates a range of safeguards to protect it from damage. These include auto-recovery short-circuit protection, under-voltage lockout and over-temperature protection. For further information, visit the Company’s website at www.diodes.com.
