Advanced 64-Step DC volume control minimizes external components and allows speaker volume control and headphone volume control. It offers low THD+N, to produce high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, without low-pass output filters which will save 30% system cost and 75% PCB area. With the same numbers of external components, the efficiency of the PAM8007 is much better than class-AB cousins. It can extend the battery life thus be ideal for portable applications. The PAM8007 is available in a SSOP-24 and SOP-24 package.
