MAX9716EUA+

Audio Amplifiers Overview

The MAX9716EUA+ is a mono audio power amplifier in an 8-pin µMAX package. It delivers 1.4W continuous power into a 4Ω load at 5V supply with less than 1% THD+N. The device operates from a single 2.7V to 5.5V supply, drawing 4.3mA quiescent current and reducing to under 10nA in shutdown mode. It features adjustable gain via external resistors, comprehensive click-and-pop suppression, and thermal protection.

Audio Amplifiers Feature Summary

• Bridge-tied load architecture minimizes external component count while providing high-quality audio reproduction
• Industry-leading click-and-pop suppression reduces audible artifacts during startup and shutdown
• Low-power shutdown mode disables bias generator and amplifiers for minimal current consumption
• Adjustable gain configuration allows flexibility through external feedback resistors

Audio Amplifiers Applications

• Portable audio devices with internal speakers
• Mobile phones
• PDAs

Audio Amplifiers Procurement Notes

Verify the specific suffix EA indicates the 8-pin µMAX package variant. Confirm lead-free status matches RoHS compliance requirements. Check for any obsolescence notices or lifecycle changes as this component may be discontinued. Ensure the ordering code aligns with the required temperature range of -40°C to +85°C.

Audio Amplifiers Selection Notes

Select this part for applications requiring a low-cost, mono amplifier solution. The adjustable gain option suits designs needing flexible signal levels. Consider the µMAX package size constraints and thermal dissipation capabilities relative to the expected output power and ambient temperature conditions.

Audio Amplifiers Part Context

This component belongs to the MAX9716/MAX9717 family of low-cost, mono, 1.4W BTL audio power amplifiers. It is designed specifically for portable audio devices. The MAX9716 variant offers adjustable gain, distinguishing it from fixed-gain counterparts like the MAX9717B/C/D within the same series.

Audio Amplifiers Replacement Considerations

The MAX9716 is pin compatible with the LM4890. Designers may consider the LM4890 as a direct replacement if available, ensuring functional equivalence in gain and package type.
