The NJM2705 is a surround audio processor for mobile applications. It regenerates the 3D surround sound with extremely narrow space two speakers (2SP mode), headphone surround with normal headphone (HP mode) and reverberation sound with only one speaker (1SP mode). It includes mode control switches for surround function and standby function and realizes low consumption power design by standby function. In addition to SSOP16, an ultra small and thin package FFP16 (Flip-Chip Fine Package) is applied. It is suitable for cellular phone, PDA and portable game.
