MAX4063 - Differential Microphone Preamplifier

General Description

The MAX4063 is a differential-input microphone preamplifier optimized for high-performance, portable applications.

Key Features

  • two selectable inputs, differential outputs, adjustable gain, an integrated lownoise bias source, and a low-power shutdown mode. Two input paths provide both differential and singleended microphone sensing. The high-noise rejection of the differential input is ideally suited to an internal microphone where system noise and long-run PC board traces can degrade low-level signals. The single-ended input provides a simple connection to an external microphone. The differential and single-ended inputs.
