The LA4495 and LA4496 are monolithic linear ICs designed for car‑stereo applications. They offer high output power, low distortion, excellent ripple rejection, and built‑in protection functions such as standby control, pop‑noise prevention, thermal shutdown, over‑voltage and load‑short protection.
The document lists maximum ratings, operating conditions, and a sample application circuit. It details required external components (feedback, filter, bootstrap, and power capacitors) and explains the IC's internal protection mechanisms, including output pin‑to‑Vcc, V‑oc, and GND short protectors.
