MAX4063EUD+T

Audio Amplifiers Overview

The MAX4063EUD+T is a differential-input microphone preamplifier in a 14-pin TSSOP package, operating from 2.4V to 5.5V over -40°C to +85°C. It features adjustable gain set by a single external resistor, with typical supply current of 750µA and shutdown current of 0.3µA. The device provides high power-supply rejection (95dB) and common-mode rejection (79dB), along with an integrated low-noise microphone bias source.

Audio Amplifiers Feature Summary

• Differential input stage for high noise rejection in digital environments
• Integrated low-noise microphone bias source eliminates external components
• Complete shutdown mode reduces supply current to minimal levels
• Selectable differential or single-ended auxiliary input paths

Audio Amplifiers Applications

• Notebook audio systems
• Tablet PCs
• PDA audio systems
• Signal conditioning

Audio Amplifiers Procurement Notes

Verify the suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm the 'E' designation corresponds to the extended temperature range (-40°C to +85°C). Ensure the 'U' package code matches the 14-lead thin-shrink small-outline package (TSSOP) requirements for your PCB layout. Cross-reference the lead-free/RoHS compliance status indicated by the '+' symbol with your manufacturing standards.

Audio Amplifiers Selection Notes

Select this component when differential signaling is required to mitigate ground noise in portable devices. The fixed 14-pin TSSOP package suits space-constrained designs where surface-mount assembly is preferred. Consider the internal bias output if external biasing circuits are undesirable. Verify that the single-resistor gain adjustment mechanism aligns with your system's calibration flexibility needs.

Audio Amplifiers Part Context

This part belongs to the MAX4063 family of differential microphone preamplifiers. The EUD variant specifically denotes the 14-pin TSSOP package configuration within the extended industrial temperature range. It shares core functionality with other package options like the 16-pin TQFN but differs in physical footprint and thermal dissipation characteristics.
