Automotive DirectDrive Headphone Amplifiers

with Output Protection and Diagnostics

0/MAX31

General Description

Features

The MAX13330/MAX13331 stereo headphone amplifiers

are designed for automotive applications requiring out-

put short-circuit and ESD protection to battery/ground

with diagnostics. These devices use Maxim’s unique

♦ 4V to 5.5V Single-Supply Operation

♦ 2MHz Charge Pump Prevents AM Radio

Interference

DirectDrive architecture to produce a ground-refer-

♦ Ground-Referenced Outputs Eliminate Bulky DC-

enced 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 or adjusted exter-

nally with resistors on the MAX13331.

Blocking Capacitors

♦ Short-to-Ground and Battery (V

up to +45V)

BAT

Output Protection, Load Dump Protection

♦ Short-Circuit Diagnostic Output

The MAX13330/MAX13331 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 effi-

cient integrated charge pump allows the device to drive

loads as low as 8Ω, enabling the use of small loud-

speakers. An 80dB at 217Hz PSRR allows these

devices to operate from noisy digital supplies without

an additional linear regulator. These devices 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 startup and shutdown. A

low-power shutdown mode reduces the supply current

to 3µA (typ).

♦ Adjustable Gain (MAX13331) or Fixed -1.5V/V Gain

(MAX13330)

♦ 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

♦

15kV Human Body Model ESD Protection for

Output Pins
