MAX4063ETE+

Audio Amplifiers Overview

The MAX4063ETE+ is a differential-input microphone preamplifier designed for portable applications. It operates from a single 2.4V to 5.5V supply and features two selectable inputs: a differential input (IN+, IN-) and an auxiliary single-ended input (AUX_IN). The device provides differential outputs with adjustable gain set by a single external resistor, achieving up to 200V/V. Key electrical parameters include a typical supply current of 750µA, shutdown current of 0.3µA, 95dB PSRR, and 79dB CMRR. It includes an integrated low-noise microphone bias source and is specified over the -40°C to +85°C temperature range in a 16-pin TQFN-EP package.

Audio Amplifiers Feature Summary

• Differential input stage providing high noise rejection for internal microphones
• Integrated low-noise microphone bias source eliminating external components
• Complete shutdown mode reducing supply current to 0.3µA
• Adjustable voltage gain via a single external resistor

Audio Amplifiers Applications

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

Audio Amplifiers Procurement Notes

Verify the specific suffix ETE+ corresponds to the 16-pin TQFN-EP package variant when sourcing. Confirm RoHS compliance status as indicated by the plus sign. Ensure the supplier provides the official Analog Devices or Maxim Integrated datasheet for accurate pinout and electrical characteristic validation before integration into designs.

Audio Amplifiers Selection Notes

Select this component when differential signaling is required to mitigate noise in compact mobile devices. The dual-input architecture allows flexibility between internal ECMs and external jack-connected microphones. Consider the space-saving TQFN package for PCB layout constraints where thermal performance via the exposed pad is beneficial.

Audio Amplifiers Part Context

The MAX4063ETE+ belongs to the MAX4063 family of differential microphone preamplifiers. It is manufactured by Analog Devices Inc., formerly Maxim Integrated. The part is specifically the lead-free, RoHS-compliant version housed in a 16-pin Thin Quad Flatpack (TQFN) with an exposed paddle for improved thermal dissipation and grounding.

Audio Amplifiers Replacement Considerations

The MAX4063EUD+ serves as a direct functional replacement within the same series, differing only in package type (14-pin TSSOP instead of 16-pin TQFN). Verify pin compatibility and thermal requirements when substituting packages.
