MAX13335EGEE/V+

Audio Amplifiers Overview

The MAX13335EGEE/V+ is a dual-channel automotive audio receiver with I2C control and diagnostics. It operates on +3.3V or +5V supplies, featuring fully differential inputs tolerant up to 7VRMS and quasi-differential inputs up to 3.5VRMS. The device provides programmable gain from -14dB to +16dB with zero-crossing detection. It includes four diagnostic I/O ports for jack sense and fault detection, high common-mode rejection of 80dB, and ISO 10605 ±15kV ESD protection. Packaged in a 16-pin QSOP.

Audio Amplifiers Feature Summary

• Dual-channel low-noise programmable gain amplifier with zero-crossing detection
• Integrated I2C interface for gain adjustment and status monitoring
• Four configurable diagnostic I/O ports for jack sense and fault detection
• High common-mode rejection ratio for noise immunity in automotive environments

Audio Amplifiers Applications

• Radio Head Units
• RSA/RSE Systems
• Connectivity Modules
• Automotive Telematics

Audio Amplifiers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +105°C) and 'V+' denotes lead-free compliance. Confirm the package type matches the required 16-pin QSOP footprint. Ensure the design supports the necessary I2C addressing configuration via the INT pin during initialization.

Audio Amplifiers Selection Notes

Select this component when differential audio input handling with robust diagnostics is required. The MAX13335E offers a wider gain range compared to the MAX13336E variant. Consider the thermal resistance characteristics if operating near the upper temperature limits. Verify compatibility with the intended I2C bus voltage levels.

Audio Amplifiers Part Context

This device belongs to the MAX13335E/MAX13336E family of dual automotive differential audio receivers. It is designed to pair with MAX13325/MAX13326 transmitters for complete audio links. The series emphasizes high fidelity and diagnostic capabilities specifically for harsh automotive electrical environments.

Audio Amplifiers Replacement Considerations

The MAX13336E is a functional alternative within the same family but features a different gain range (-22dB to +8dB). Verify that the gain specifications and I2C register maps are compatible with the existing system design before substitution.
