NXP’s key technical merits in the Class D amplifier market include: a process technology with medium and high power amplifiers using the Silicon on Isolator (SOI) process; maximum power without heat sink designs (high efficiency due to the use of low Rds(on) FETs); no need for shielding or EMI compliancy; and ease of use with dedicated reference designs and customer support. Their performance is matched for specific applications and designs with no on/off plop sounds; high output power and efficiency; audiophile sound quality equal to Class AB; high supply noise suppression; and thermal foldback.
