Maxim Integrated MAX9710ETP+T Audio Amplifier

The MAX9710ETP+T from Maxim Integrated is a high-performance, stereo audio power amplifier designed to deliver exceptional sound quality for a wide range of applications. This compact audio solution is ideal for portable and space-constrained applications such as mobile phones, laptops, portable media players, and other devices where high-quality audio amplification is required.

The MAX9710ETP+T operates from a single 4.5V to 5.5V supply, making it suitable for use with most standard power sources. It delivers up to 2 x 1.4W into a 4Ω load or 2 x 1.8W into a 3Ω load with less than 1% total harmonic distortion plus noise (THD+N), ensuring a clear and powerful audio output. The device also features a high 90dB power supply rejection ratio (PSRR), which minimizes noise and interference from fluctuating power supplies, maintaining the integrity of the audio signal.

This audio amplifier integrates a comprehensive set of protections to ensure reliability and longevity. These include thermal overload protection, under-voltage lockout, and a click-and-pop suppression circuit that reduces noise when turning the amplifier on or off. Additionally, the MAX9710ETP+T offers a low quiescent current draw, which extends battery life in portable applications.

The device comes in a space-saving 20-pin TQFN package with exposed pad (EP) and is specified over the extended -40°C to +85°C temperature range. The lead-free, RoHS-compliant design aligns with modern environmental standards, making the MAX9710ETP+T a responsible choice for eco-conscious manufacturers.

With its high-quality audio performance, compact form factor, and robust protection features, the MAX9710ETP+T from Maxim Integrated is an excellent choice for designers looking to enhance the audio experience in their products without compromising on space or power efficiency.
