MAX9717DEUA+

Audio Amplifiers Overview

The MAX9717DEUA+ is a mono, low-cost audio power amplifier in an 8-pin µMAX package. It operates from a single 2.7V to 5.5V supply and delivers 1.4W continuous power into a 4Ω load at 1% THD+N. The device features internally fixed gain of 12dB, reducing external component count. It includes comprehensive click-and-pop suppression and a low-power shutdown mode that reduces quiescent current to less than 10nA. A BTL/SE input allows sensing headphone connection to switch between bridge-tied load and single-ended modes.

Audio Amplifiers Feature Summary

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

Audio Amplifiers Applications

• Mobile phones
• PDAs
• Portable devices with internal speakers

Audio Amplifiers Procurement Notes

Verify the specific suffix DEUA corresponds to the 8-pin µMAX package with 12dB fixed gain as documented in the official selector guide. Confirm lead-free/RoHS compliance status for the + designation. Check current product lifecycle status as older Maxim products may be discontinued or subject to PCN notifications.

Audio Amplifiers Selection Notes

Select this part for designs requiring a fixed 12dB gain without external resistors. Ensure the application fits within the 8-pin µMAX thermal dissipation limits. Verify that the single-ended input requirement aligns with the MAX9717 architecture, as differential inputs are not supported on this variant.

Audio Amplifiers Part Context

This component belongs to the MAX9716/MAX9717 family of low-cost, mono, 1.4W BTL audio power amplifiers. The MAX9717 variants specifically include a BTL/SE control input for headphone detection, distinguishing them from the pin-compatible but feature-limited MAX9716.

Audio Amplifiers Replacement Considerations

The MAX9716 is pin-compatible but lacks the BTL/SE input and has adjustable gain. Other MAX9717 variants (B/C) offer different fixed gains (6dB/9dB). No direct public substitute part numbers are confirmed in the provided documentation.
