MAX9812LEXT-T Microphone Amplifier IC from Maxim Integrated

The MAX9812LEXT-T is a high-quality, low-noise microphone amplifier integrated circuit (IC) from Maxim Integrated, a renowned leader in analog and mixed-signal engineering. This IC is designed to serve as a compact, efficient, and reliable solution for various audio applications, including mobile phones, tablets, laptops, and other portable devices where space is at a premium and audio quality is essential.

The MAX9812LEXT-T features a single/dual-input, 20dB fixed-gain microphone amplifier that is optimized to provide a low noise floor and a high-quality audio signal. With its low 1.4nV/√Hz input-referred noise and low 200µA supply current, the MAX9812LEXT-T ensures that the audio captured is both clear and power-efficient, making it an ideal choice for battery-powered applications.

The IC operates from a single 2.7V to 3.6V supply, which allows for seamless integration into most modern electronic devices. Additionally, the MAX9812LEXT-T boasts an impressive total harmonic distortion plus noise (THD+N) of only 0.015%, ensuring that the audio output remains pure and undistorted even at high volumes.

One of the standout features of the MAX9812LEXT-T is its integrated RF suppression, which protects against interference from mobile phones and other RF-emitting devices. This ensures that the audio signal remains clean and free from unwanted noise, even in environments with high RF activity. Furthermore, the IC comes in a tiny, space-saving 5-pin SC70 or 6-bump UCSP package, which is perfect for applications where board space is a critical constraint.

For designers and engineers looking for a high-performance audio amplification solution, the MAX9812LEXT-T offers an excellent balance of sound quality, power efficiency, and miniaturization. Its ease of use, coupled with Maxim Integrated's reputation for reliability, makes it a go-to choice for those looking to enhance the audio experience in their next project.
