MAX9717AEUA+T

Audio Amplifiers Overview

The MAX9717AEUA+T is a mono audio power amplifier in an 8-pin µMAX package. It operates on a single supply from 2.7V to 5.5V and delivers 1.4W into a 4Ω load at 1% THD+N. The device features adjustable gain, low-power shutdown mode with less than 10nA current consumption, and comprehensive click-and-pop suppression. It includes a headphone sense input for BTL/SE switching.

Audio Amplifiers Feature Summary

• Bridge-tied load architecture minimizes external component count while providing high-quality audio reproduction
• Headphone sense input automatically disables the BTL slave driver when headphones are connected
• Low-power shutdown mode reduces quiescent current consumption significantly
• Industry-leading click-and-pop suppression eliminates audible noise during startup and shutdown

Audio Amplifiers Applications

• Mobile phones
• PDAs
• Portable devices

Audio Amplifiers Procurement Notes

Verify the specific ordering suffix '+T' indicates tape and reel packaging configuration. Confirm the 'EUA' designation corresponds to the 8-pin µMAX-EP package type. Ensure the 'A' variant matches the required adjustable gain specification rather than fixed gain options. Cross-reference the manufacturer's latest datasheet revision for any pinout or electrical characteristic updates.

Audio Amplifiers Selection Notes

Select this part when adjustable gain is required for the MAX9717 family. Choose the µMAX package for applications needing exposed pad thermal dissipation in a small outline form factor. Consider the headphone sense feature if automatic speaker-to-headphone switching is necessary. Verify that the single-ended input requirement aligns with the MAX9717 architecture limitations.

Audio Amplifiers Part Context

This component belongs to the MAX9716/MAX9717 series of low-cost, mono, 1.4W BTL audio power amplifiers designed for portable audio devices. The MAX9717 variant specifically adds a headphone sense input compared to the MAX9716. The 'A' suffix denotes the adjustable gain version, distinct from the internally fixed gain variants (B, C, D).

Audio Amplifiers Replacement Considerations

The MAX9716 is pin compatible with the LM4890. The MAX9717A is pin compatible with the TPA711. Verify functional equivalence regarding gain adjustability and headphone sensing capabilities before substitution.
