Microphone Amplifiers for Notebook Computers
Maxim offers a wide variety of low-power, highly integrated microphone amplifiers that feature industry leading PSRR and ultra-low THD+N. An integrated microphone bias eliminates the need for an additional supply, simplifying system design and lowering solution cost. Available in single and dual versions with single-ended or differential inputs, Maxim's microphone amplifiers are ideal for any notebook design.
