Maxim Integrated MAX4062EUB+ Overview

The MAX4062EUB+ is a high-performance, low-voltage, differential microphone preamplifier with integrated bias. Designed by Maxim Integrated, a leader in analog and mixed-signal processing technology, this preamplifier is ideal for portable digital audio applications such as notebook computers, mobile phones, and PDAs where space is at a premium and excellent audio quality is a must.

Key Features

• Low Operating Voltage: The MAX4062EUB+ operates from a single 1.8V to 3.6V supply, making it suitable for use in battery-powered devices.
• High PSRR (Power Supply Rejection Ratio): With an impressive PSRR, this preamplifier ensures that fluctuations in power supply voltage do not affect the audio signal quality.
• Low Noise Performance: It offers a low input-referred noise density of 8nV/√Hz, which is critical for maintaining the clarity and integrity of audio signals.
• Differential Inputs: The differential input structure provides improved noise rejection and is less susceptible to electromagnetic interference, making it suitable for use in challenging environments.
• Integrated Bias: The device includes an integrated microphone bias voltage generator, simplifying circuit design and reducing external component count.
• Adjustable Gain: The preamplifier offers two selectable gains of 6dB or 14dB, allowing for flexibility in various application requirements.
• Compact Package: Housed in a tiny 10-pin µMAX package, the MAX4062EUB+ saves valuable board space in space-constrained applications.
