MAX9717AEBL+T

Audio Amplifiers Overview

The MAX9717AEBL+T is a mono audio power amplifier in a 3x3mm UCSP package. It operates on 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 adjustable gain, BTL/SE headphone sensing, and click-and-pop suppression. Quiescent current is less than 8mA, dropping to under 10nA in shutdown mode. Operating temperature range is -40°C to +85°C.

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.
• Comprehensive click-and-pop suppression reduces audible artifacts during startup and shutdown.
• Low-power shutdown mode significantly reduces quiescent current consumption.

Audio Amplifiers Applications

• Mobile phones
• PDAs
• Portable devices

Audio Amplifiers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and thermal characteristics. Ensure the component matches the required gain configuration and operating voltage range for your design. Cross-reference the manufacturer's latest datasheet for any updates regarding pin compatibility or environmental compliance standards before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component for portable applications requiring high output power in a minimal footprint. The adjustable gain option allows flexibility in circuit design compared to fixed-gain variants. Consider the UCSP package for space-constrained layouts where thermal dissipation can be managed through PCB ground planes.

Audio Amplifiers Part Context

This part belongs to the MAX9716/MAX9717 family of low-cost, mono, 1.4W BTL audio power amplifiers. It shares core functionality with other variants in the series but is distinguished by its adjustable gain setting and specific UCSP packaging. The family is designed for internal speaker driving in battery-powered devices.

Audio Amplifiers Replacement Considerations

The MAX9716 is pin-compatible with the LM4890. The MAX9717A variant is pin-compatible with the TPA711. Verify functional equivalence and pinout alignment before substituting.
