MAX4060ETA+T

Audio Amplifiers Overview

The MAX4060ETA+T is a differential-input microphone preamplifier from the MAX4060/MAX4061/MAX4062 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 4.5V to 5.5V supply and features a fixed gain of 10V/V (20dB). The device includes an integrated microphone bias generator compliant with PC99/2001 standards, delivering approximately 2.2V at 0.8mA load. Key electrical specifications include a typical supply current of 750μA, high power-supply rejection ratio (PSRR) of 86dB at 1kHz, and common-mode rejection ratio (CMRR) of 70dB. It offers rail-to-rail outputs, low input-referred noise (100nV/√Hz), and ±4kV ESD protection on the auxiliary input. The component is housed in an 8-pin TDFN package with an exposed pad.

Audio Amplifiers Procurement Notes

Verify the specific suffix 'ETA' corresponds to the 8-pin TDFN package variant when sourcing. Confirm RoHS compliance status indicated by the '+' suffix. Ensure the application voltage range aligns with the 4.5V to 5.5V requirement, as this model differs from the lower-voltage MAX4061/MAX4062 variants. Check for lead-free certification documentation if required by regional regulations.

Audio Amplifiers Selection Notes

Select the MAX4060ETA+T when a fixed 10V/V gain is sufficient and operation requires a 4.5V to 5.5V supply. Choose this over the MAX4061 or MAX4062 if shutdown functionality or adjustable gain is not needed. The TDFN package is suitable for space-constrained designs requiring an exposed pad for thermal management. Ensure the system can accommodate the higher supply voltage compared to the 2.4V capable counterparts.

Audio Amplifiers Part Context

The MAX4060 is part of a series of differential microphone preamplifiers designed for portable audio applications. It complements the MAX4061 and MAX4062, which offer adjustable gain and lower voltage operation. The MAX4060 specifically targets systems requiring PC99/2001 compliance and fixed gain simplification. It is manufactured using BiCMOS process technology, providing robust performance in noisy digital environments typical of computers and mobile devices.
