MAX9717CEBL+T

Audio Amplifiers Overview

The MAX9717CEBL+T is a mono, Class-AB audio power amplifier in a 9-bump UCSP 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 with a 5V supply. The device features internally fixed gain of 9dB, BTL/SE headphone sensing, and comprehensive click-and-pop suppression. Quiescent current drops below 10nA in shutdown mode.

Audio Amplifiers Feature Summary

• Bridge-tied load architecture minimizes external component count while delivering high-quality audio reproduction.
• Headphone sense input automatically disables the BTL slave driver to mute the speaker when headphones are connected as a single-ended load.
• Industry-leading click-and-pop suppression circuitry reduces audible artifacts during startup and shutdown sequences.
• Low-power shutdown mode disables bias generators and amplifiers to minimize quiescent current consumption.

Audio Amplifiers Applications

• Mobile phones
• PDAs
• Portable devices

Audio Amplifiers Procurement Notes

Verify the specific suffix +T indicates tape-and-reel packaging and + denotes lead-free/RoHS compliance. Confirm the CEBL variant corresponds to the 9-bump UCSP package. Check for obsolescence status as this part may be discontinued.

Audio Amplifiers Selection Notes

Select this model for applications requiring a fixed 9dB gain without external resistors. Ensure the design accommodates the 9-bump UCSP thermal requirements. Verify that the single-ended input configuration matches the system audio source interface.

Audio Amplifiers Part Context

This component belongs to the MAX9716/MAX9717 family of low-cost, mono, 1.4W BTL audio power amplifiers designed for portable audio devices with internal speakers. The MAX9717 variant specifically includes the BTL/SE control input for headphone detection functionality not present in the MAX9716.

Audio Amplifiers Replacement Considerations

The MAX9716 is pin-compatible but lacks the BTL/SE input. Other MAX9717 variants include MAX9717B (6dB gain) and MAX9717D (12dB gain). Package alternatives include TDFN and µMAX formats.
