MAX13330GEE/V+

The MAX13330 stereo headphone amplifiers are designed for automotive applications requiring output short-circuit and ESD protection to battery/ground with diagnostics. These devices use Maxim’s unique DirectDrive® architecture to produce a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving board space and component height. The gain of the amplifier is set internally (-1.5V/V) on the MAX13330. The MAX13330 deliver 120mW per channel into a 16Ω load or 135mW into a 32Ω load and have a low 0.01% THD+N. Low output impedance and the efficient integrated charge pump allows the device to drive loads as low as 8Ω, enabling the use of small loudspeakers.

• 4V to 5.5V Single-Supply Operation
• 2MHz Charge Pump Prevents AM Radio Interference
• Ground-Referenced Outputs Eliminate Bulky DCBlocking Capacitors
• Short-to-Ground and Battery (VBAT up to +45V) Output Protection, Load Dump Protection
• Short-Circuit Diagnostic Output
• 125mW per Channel into 32Ω at 0.01% THD+N
• Integrated Click-and-Pop Suppression
• High PSRR Eliminates LDO
• No Degradation of Low-Frequency Response Due to Output Capacitors
