MAX9717DETA+T

Audio Amplifiers Overview

The MAX9717DETA+T is a mono audio power amplifier in an 8-pin TDFN 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. The BTL/SE input senses 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
• Internal fixed gain configuration eliminates the need for external gain-setting resistors
• Headphone sense input automatically switches output configuration when headphones are connected
• Comprehensive click-and-pop suppression circuitry prevents audible noise during power transitions

Audio Amplifiers Applications

• Portable audio devices with internal speakers
• Mobile phones
• Personal digital assistants (PDAs)

Audio Amplifiers Procurement Notes

Verify the specific suffix 'DETA' against official documentation to confirm pinout, gain setting, and package details. Ensure compatibility with existing board layouts and thermal requirements. Confirm availability status as product lifecycles may change. Cross-reference ordering information to validate exact specifications before procurement.

Audio Amplifiers Selection Notes

Select this part for applications requiring a fixed 12dB gain without external resistors. The integrated headphone sense simplifies designs needing automatic speaker-to-headphone switching. Consider the 8-pin TDFN package for space-constrained portable electronics. Verify thermal dissipation capabilities relative to the expected ambient temperature and load impedance.

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 headphone sense input not present in the MAX9716. The 'D' suffix indicates an internally fixed gain of 12dB, distinguishing it from adjustable or other fixed gain versions within the same series.

Audio Amplifiers Replacement Considerations

MAX9717CETA+T offers a similar 8-pin TDFN package but with an internally fixed gain of 9dB instead of 12dB.
