NCP2815BFCCT2G

Overview

The NCP2815BFCCT2G is a stereo Class AB audio amplifier designed for mobile applications. It operates within a supply voltage range of 1.6 V to 3.6 V and delivers 62 mW of output power per channel into a 16-ohm load. The device utilizes a 12-pin Flip-Chip package with dimensions of 1.62 mm by 1.22 mm. Key electrical characteristics include a low quiescent current and support for single-supply operation, making it suitable for battery-powered portable electronics requiring high efficiency and minimal space.

Feature Summary

• LongPlay technology enables extended battery life through optimized power management in standby and active modes.
• True Ground architecture provides improved audio performance and stability without the need for external coupling capacitors.
• Backside laminate coating enhances thermal dissipation and mechanical reliability in compact form factors.

Applications

• Mobile phone headphone amplifiers
• Portable media players
• Smartphones and tablets

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the 12-pin Flip-Chip (CSP) package footprint aligns with your PCB layout constraints. Confirm RoHS compliance status if required by your regional regulations. Cross-reference the part number with official onsemi documentation to avoid counterfeit components.

Selection Notes

Select this component when designing for ultra-low voltage operation below 2.0 V where standard amplifiers may fail. The integrated True Ground feature eliminates the need for large external capacitors, saving board space. Consider the 12-pin CSP package for high-density layouts. Verify that the 62 mW output power meets the sensitivity requirements of the connected headphones or speakers.
