This compact audio amplifier IC is ideal for portable devices such as smartphones, tablets, laptops, and portable media players, where space is at a premium and power efficiency is crucial.

Featuring Maxim's patented DirectDrive® technology, the MAX4410 eliminates the need for large DC-blocking capacitors, thereby saving space and cost while also improving low-frequency audio fidelity. This technology creates a ground-referenced output from a single supply, enabling the device to deliver a high-quality audio signal with a minimal number of external components.

The MAX4410EUD+TG40 operates from a single 2.7V to 5.5V supply, making it versatile for various battery-powered applications. Its high efficiency helps to extend battery life, which is critical for mobile devices. Additionally, the amplifier offers a low 0.01% total harmonic distortion plus noise (THD+N) at 1kHz, ensuring clear and crisp sound reproduction.

With an output power of up to 80mW per channel into a 16Ω load, this amplifier can drive a wide range of headphones with different impedances, from 16Ω to 600Ω. The device also features a low-power shutdown mode, further conserving energy when not in use.

The MAX4410EUD+TG40 comes in a compact TSSOP-14 (Thin Shrink Small Outline Package) and is specified over the extended -40°C to +85°C temperature range, making it suitable for both consumer and industrial applications. Its built-in click-and-pop suppression minimizes audible clicks and pops during startup and shutdown, ensuring a smooth user experience.

With its combination of high-quality audio performance, power efficiency, and small form factor, the MAX4410EUD+TG40 is an excellent choice for designers looking to enhance the audio capabilities of their next-generation portable devices.
