MAX98310EWL+T

Audio Amplifiers Overview

The MAX98310EWL+T is a mono 1.4W Class AB audio amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.5V to 5.5V and features internally fixed differential gain options of 0dB, 3dB, 6dB, or 9dB selectable via the GAIN pin. The device delivers 750mW into an 8Ω load at 3.7V with 1% THD+N. It incorporates industry-leading click-and-pop suppression, high 90dB PSRR, and low quiescent current of 1.2mA at 3.7V. Packaged in a compact 1mm x 1mm 9-bump WLP, it supports operation across an extended temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Features state-of-the-art click-and-pop suppression circuitry for minimized startup noise
• Provides excellent power-supply rejection ratio (PSRR) to maintain audio quality under varying supply conditions
• Includes thermal overload and short-circuit protection for robust system design
• Utilizes a fully differential input architecture to improve noise immunity

Audio Amplifiers Applications

• Cell Phones/Smartphones
• Digital Cameras
• Portable Media Players
• e-Readers
• Tablets

Audio Amplifiers Procurement Notes

Verify that the ordering suffix '+T' corresponds to tape-and-reel packaging as specified in official manufacturer documentation. Confirm the component is lead-free and RoHS-compliant based on the '+' designation. Ensure the specific gain configuration matches the internal fixed settings available for the MAX98310 variant rather than the external resistor requirements of the MAX98309.

Audio Amplifiers Selection Notes

Select this component when a compact footprint is required for portable audio applications. Choose the MAX98310 over the MAX98309 if fixed internal gain settings are acceptable, eliminating the need for external gain-setting resistors. Consider the 1mm x 1mm WLP package for space-constrained designs where thermal dissipation can be managed through PCB layout.

Audio Amplifiers Part Context

This part belongs to the MAX98309/MAX98310 family of mono Class AB audio amplifiers. While sharing identical electrical characteristics and physical packages, the MAX98310 differs from the MAX98309 by utilizing internally fixed gain levels instead of externally adjustable gain via resistors. Both variants share the same 9-bump WLP package and operational specifications.

Audio Amplifiers Replacement Considerations

The MAX98309EWL+T serves as a direct functional substitute within the same family, differing only in gain configuration method. Verify that the application design accommodates the fixed gain options of the MAX98310 if replacing a variable-gain design.
