NCP2892AFCT2G

Overview

The NCP2892AFCT2G is a single-channel Class-AB audio power amplifier manufactured by onsemi. It delivers 1.3 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.04%. The device operates within a supply voltage range of 2.2 V to 5.5 V and draws a quiescent current of 1.7 mA. It supports differential or single-ended input configurations and provides an output current capability of 500 mA. The component is housed in a compact 9-ball WLCSP package measuring 1.45 x 1.45 mm, suitable for surface-mount installation.

Feature Summary

• Delivers high-fidelity audio performance with low distortion characteristics
• Features rapid turn-on time to minimize audible switching transients
• Supports flexible input configurations including differential and single-ended modes

Applications

• Portable consumer electronics requiring mono audio amplification
• Industrial temperature range audio systems
• Battery-powered devices utilizing single-supply architectures

Procurement Notes

Verify the specific suffix 'AFCT2G' against official onsemi documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Ensure the WLCSP-9 footprint matches your PCB layout requirements precisely. Check for end-of-life notices or obsolescence announcements directly from onsemi before finalizing procurement plans.

Selection Notes

Select this component when a compact mono amplifier with fast startup is required. It is suitable for applications needing 1.3 W output into 8 ohms. Consider the 2.2 V minimum supply voltage for battery-operated designs. The small WLCSP package aids in space-constrained layouts. Verify thermal management needs for continuous operation at maximum power levels.

Part Context

This part belongs to the NCP2890 series of audio amplifiers from onsemi. The series focuses on delivering efficient audio performance in minimal footprints. The NCP2892 variant specifically emphasizes fast turn-on capabilities compared to standard models. It targets portable and industrial applications where size and startup behavior are critical design parameters.

Replacement Considerations

Consult onsemi technical support for verified cross-reference part numbers. Do not assume functional equivalence with other NCP28xx variants without verifying pin compatibility and electrical limits.
