Class D audio amp reduces component count
Integrating an advanced 32step up/down volume control, the PAM8407 Class D audio amplifier from Diodes is optimised to reduce component count in a range of stereo speaker applications, including PCs, docking stations and wireless speakers.
Able to drive dual 4O 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 amplifier's filterless output architecture also saves space by minimising 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 suited to portable applications. Its wide operating voltage range of 2.5 and 6V makes it ideal for a 4x alkaline cell configuration.
