Audio Amplifiers datasheet and documents for MAX97220DETE+

MAX97220DETE+

Audio Amplifiers Overview

The MAX97220DETE+ is a differential input DirectDrive line driver and headphone amplifier manufactured by Analog Devices/Maxim Integrated. It operates on a single supply voltage ranging from 2.5V to 5.5V. The device provides an output power of 125mW into a 32-ohm load with a 5V supply. It features a fixed internal gain of +6dB and a turn-on time of 130ms, optimized for set-top box applications. The unit is housed in a 16-pin TQFN package.

Audio Amplifiers Feature Summary

DirectDrive architecture eliminates the need for large DC-blocking capacitors by using an internal charge pump to create a negative rail.
Fully differential inputs provide improved noise immunity and common-mode rejection.
Integrated click-and-pop suppression circuitry prevents audible transients during power-up and shutdown transitions.

Audio Amplifiers Applications

Set-Top Boxes
Blu-ray and DVD Players
LCD Televisions

Audio Amplifiers Procurement Notes

Verify the specific suffix 'D' indicates the 130ms turn-on time required for set-top box synchronization. Confirm the '+AII' top mark corresponds to the fixed +6dB gain configuration. Ensure the TQFN-EP package thermal pad connection is properly implemented on the PCB layout.

Audio Amplifiers Selection Notes

Select this variant over A/B/E versions when a longer startup delay is necessary for system synchronization. The fixed +6dB gain simplifies external resistor selection compared to adjustable gain models. Verify that the 130ms transition timing aligns with the target application's audio routing requirements.

Audio Amplifiers Part Context

This component belongs to the MAX97220 family of stereo headphone amplifiers. It shares the same footprint as the legacy MAX9722 but utilizes an integrated charge pump instead of an external SVSS pin. The D version is specifically differentiated by its extended turn-on time and fixed gain settings.
