Overview
The NCP2890AFCT2 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 THD+N of 0.04%. The device operates on a single supply voltage 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 inputs and provides an output current of 500 mA. Packaged in a WLCSP-9 format, it functions within a temperature range of -40°C to +85°C.
Feature Summary
- Class-AB topology for high-fidelity audio reproduction
- Supports both differential and single-ended input configurations
- Industrial-grade operational capability across extended temperature ranges
Applications
- Industrial audio equipment requiring robust thermal performance
- Portable devices utilizing single-supply battery operation
- Mono audio signal amplification in compact form factors
Procurement Notes
Verify component authenticity through authorized channels as the part status is End-of-Life. Confirm package integrity upon receipt due to the small WLCSP footprint. Ensure design compatibility with the specified 2.2 V to 5.5 V supply range and 8 Ohm load impedance before integration.
Selection Notes
Select this component when industrial temperature stability is required alongside low distortion metrics. The single-channel architecture suits mono applications where space constraints favor the WLCSP-9 package over larger alternatives. Verify that the 1.08 W output power meets the specific acoustic requirements of the target system.
Part Context
This model belongs to the NCP2890 series of audio amplifiers from onsemi. The series focuses on delivering efficient audio performance in minimal footprints suitable for modern electronic designs. The NCP2890AFCT2 variant specifically addresses industrial environmental conditions while maintaining standard audio interface compatibility.
Replacement Considerations
Consult official substitution lists for compatible components. Verify pinout and electrical parameter alignment if considering alternative manufacturers.
