Audio Amplifiers
Audio amplifier ICs amplify audio signals to drive speakers, and headphones. The portfolio includes efficient mono and stereo Class-D speaker amplifiers, low-power linear and BTL amplifiers, boosted amplifiers with integrated charge pumps, and low-noise stereo headphone drivers. Filterless Class-D architectures reduce external component count and PCB area. Automotive devices additionally support wide supply voltages, load-dump protection, EMC mitigation, I²C diagnostics, and dynamic thermal management.
