The MAX13330/MAX13331 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, patented 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 or adjusted externally with resistors on the MAX13331.
The MAX13330/MAX13331 delivers 120mW per channel into a 16
load or 135mW into a 32 load and has a low 0.01% THD+N. Low output impedance and the efficient integrated charge pump allows the device to drive loads as low as 8, enabling the use of small loudspeakers. 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).
The MAX13330/MAX13331 are specified from -40°C to +105°C AEC-Q100 Level 2 automotive temperature range and are available in a 16-pin QSOP package.
