Overview
The NCP2890DMR2 is a Class-AB mono audio power amplifier manufactured by onsemi, designed for portable communication devices. It delivers 1.08 W of output power into an 8-ohm load with a total harmonic distortion plus noise 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 input configurations and provides a maximum output current of 500 mA. The component is housed in an 8-pin MSOP (Micro8) package and is rated for industrial operating temperatures between -40°C and +85°C.
Feature Summary
- Class-AB topology providing high-fidelity audio reproduction with low distortion characteristics
- Supports both differential and single-ended input signal configurations for flexible system integration
- Operates efficiently within a wide single-supply voltage range suitable for battery-powered applications
Applications
- Portable mobile phone audio systems
- Handheld communication devices
- Battery-operated consumer electronics requiring compact audio amplification
Procurement Notes
Verify the specific ordering suffix DMR2 to confirm the MSOP-8 package type and tape-and-reel packaging format. Confirm that the component meets RoHS compliance requirements as specified in the official datasheet. Check for end-of-life status or obsolescence notices from onsemi prior to final procurement decisions. Ensure the supplier provides valid traceability documentation for industrial temperature grade components.
Selection Notes
Select this component when a compact, low-power Class-AB amplifier is required for single-supply portable applications. The MSOP-8 package offers space efficiency compared to larger footprints. Consider the 2.2 V minimum supply voltage for compatibility with single-cell lithium-ion batteries. Verify that the 8-ohm load impedance matches the target speaker specifications to achieve the rated 1.08 W output performance.
Part Context
The NCP2890 belongs to onsemi's portfolio of audio power amplifiers optimized for mobile and portable electronics. This series focuses on delivering high audio quality within strict power and size constraints typical of handheld devices. The NCP2890DMR2 variant specifically utilizes the Micro8 package to minimize board space while maintaining thermal performance for industrial temperature ranges.
Replacement Considerations
The NCP2890AFCT2G is a documented alternative within the same family, offering identical electrical performance but utilizing a WLCSP-9 package instead of MSOP-8. Verify pinout compatibility and mechanical footprint differences before substitution.
