MAX4063ETE+T

Audio Amplifiers Overview

The MAX4063ETE+T is a differential-input microphone preamplifier optimized for portable applications. It operates from a single 2.4V to 5.5V supply and features two selectable inputs (differential or single-ended) with adjustable gain set by a single external resistor. The device provides differential outputs capable of up to 6V P-P swing, an integrated low-noise bias source, and a complete shutdown mode reducing current to 0.3µA. Key electrical parameters include a typical supply current of 750µA, 95dB PSRR, 79dB CMRR, and THD+N of 0.05% at 1kHz. It is specified over the -40°C to +85°C temperature range.

Audio Amplifiers Feature Summary

• Provides high-noise rejection through differential input and output stages, suitable for internal microphones in noisy environments.
• Features an integrated low-noise microphone bias source that simplifies system design by eliminating external components.
• Includes a complete shutdown mode that disables the microphone bias and reduces supply current to 0.3µA for maximum power savings.

Audio Amplifiers Applications

• Notebook audio systems
• Tablet PCs
• PDA audio systems
