MAX13331GEE/V+

The MAX13331GEE/V+ is a automotive DirectDrive headphone amplifiers with output protection and diagnostics in 16 pin QSOP package. This stereo headphone amplifier is designed for automotive applications requiring output short circuit and ESD protection to battery/ground with diagnostics. Device use Maxim’s unique DirectDrive architecture to produce a ground referenced output from a single supply, eliminating need for large DC-blocking capacitors, saving board space and component height. The gain of the amplifier is adjusted externally with resistors on IC. The device include ±15kV Human Body Model ESD protection and short circuit protection up to +45V at the headphone outputs. Comprehensive click-and-pop circuitry suppresses audible clicks and pops on start-up and shutdown. A low power shutdown mode reduces the supply current to 3µA (typ). It is used in automotive entertainment systems and automotive rear seat entertainment systems.
