Maxim Integrated MAX9820ETB+T Mono Audio Amplifier

The MAX9820ETB+T from Maxim Integrated is a high-quality, mono audio amplifier designed to deliver exceptional sound quality with minimal power consumption. It is a compact, efficient solution perfect for portable audio devices, mobile phones, and any application where space and power efficiency are critical.

This audio amplifier is part of Maxim's DirectDrive® series, which eliminates the need for bulky DC-blocking capacitors, thus reducing the overall size and component count of the audio subsystem. The MAX9820ETB+T operates from a single 2.7V to 5.5V supply, making it versatile for various battery-operated devices.

With a 1.4W output power into a 4Ω load and THD+N (Total Harmonic Distortion plus Noise) of less than 1%, the MAX9820ETB+T ensures loud, clear audio output with minimal distortion, which is essential for high-fidelity audio applications. Additionally, the device features a low 0.01% THD+N at 1kHz, which contributes to its excellent audio performance.

The MAX9820ETB+T also includes built-in features such as click-and-pop suppression, which reduces the audible clicks and pops during device startup and shutdown, providing a smoother user experience. The amplifier's high 85dB PSRR (Power Supply Rejection Ratio) ensures stable performance by minimizing noise and interference from fluctuating power supplies.

For ease of integration, the MAX9820ETB+T comes in a compact, 10-pin TDFN (Thin Dual Flat No-Lead) package, which is ideal for space-constrained applications. The device also supports a low-power shutdown mode, which further conserves battery life when the amplifier is not in use.

In summary, the MAX9820ETB+T mono audio amplifier is a high-performance, feature-rich solution for any application that requires high-quality audio amplification with minimal power draw and space requirements. Maxim Integrated's commitment to quality and innovation is evident in this audio amplifier, making it a top choice for designers and engineers in the audio industry.
