• Active-high standby mode for ultra-low power consumption
• Internal thermal shutdown protection
• Near-zero click-and-pop performance
• Unity-gain stable with configurable external gain

Applications

• Mobile phones
• Portable electronic devices
• Notebook computers

Procurement Notes

Verify the specific suffix -GRLS2-TR corresponds to the SOP-8 lead-free tape and reel packaging configuration. Confirm that the component meets RoHS and Halogen-Free compliance standards as specified in the datasheet revision C documentation before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high efficiency and minimal external components. Ensure the design accommodates the wake-up time requirements associated with the bypass capacitor charging. Verify that the BTL configuration matches the system's speaker impedance and power supply voltage constraints.

Part Context

This part belongs to the IS31AP4996 series of audio amplifiers designed for mobile and portable electronics. It utilizes a bridge-tied load (BTL) architecture to maximize output power relative to the supply voltage. The SOP-8 package provides a compact solution for space-constrained designs while maintaining robust thermal performance.

Replacement Considerations

IS31AP4996-SLS2-TR serves as a pin-compatible alternative utilizing the MSOP-8 package.
