MAX4410 HiFi Headphone Amplifier Board

SKU 591911

Build your own stereo preamplifer or build a compact headphone amplifier with the MAX4410 HiFi Headphone Amplifier Board from PMD Way.

It's perfect for taking a stereo line-level audio signal and boosting it for your headphones, or connection to a power amplifier for speaker output. 

The MAX4410 uses a unique DirectDrive architecture to produce a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height.

The MAX4410 delivers up to 80mW per channel into a 16Ω load and has low 0.003% THD+N. A high power-supply rejection ratio (90dB at 1kHz) allows this device to operate from noisy digital supplies without an additional linear regulator.

The MAX4410 includes ±8kV ESD protection on the headphone outputs. Comprehensive click-and-pop circuitry suppresses audible clicks and pops on startup and shutdown. Independent left/right, low-power shutdown controls make it possible to optimize power savings in mixed mode, mono/stereo applications.

The MAX4410 operates from a single 1.8V to 3.6V supply, consumes only 7mA of supply current, has short-circuit and thermal overload protection - perfect for your headphone amplifier needs.
