NCP2890AFCT2G

Overview

The NCP2890AFCT2G is a Class-AB mono audio amplifier manufactured by onsemi, designed for industrial temperature ranges. It delivers an output power of 1.08 W into an 8 Ohm load with a total harmonic distortion plus noise of 0.04%. The device operates on a single power supply ranging from 2.2 V to 5.5 V and draws a working supply 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 WLCSP-9 package suitable for surface mount installation.

Feature Summary

• Class-AB topology ensures high-fidelity audio reproduction with low distortion characteristics.
• Supports both differential and single-ended input signal configurations for flexible integration.
• Operates within an extended industrial temperature range from -40°C to +85°C.

Applications

• Industrial audio equipment requiring robust thermal performance
• Portable devices utilizing single-supply operation
• Audio systems needing low quiescent current consumption

Procurement Notes

Verify the specific suffix 'T2G' against official onsemi documentation to confirm lead-free compliance and tape-and-reel packaging specifications. Confirm that the WLCSP-9 footprint matches your PCB design constraints. Ensure the selected variant meets the required industrial temperature grade if operating in extreme environments. Cross-reference the datasheet revision date to validate all electrical parameters before finalizing procurement.

Selection Notes

Select this component when a single-channel audio solution is required with minimal external components. The WLCSP-9 package offers space efficiency for dense circuit designs. Consider the 2.2 V minimum supply voltage for battery-powered applications. Verify that the 8 Ohm load impedance aligns with the speaker or transducer requirements. Evaluate the 1.08 W output power against the specific acoustic needs of the target application.
