NCP2830MUTXG

Overview

The NCP2830MUTXG is a mono Class-D audio power amplifier manufactured by onsemi, designed for portable communication devices. It delivers 1.2 W of output power into a 4-ohm load with a supply voltage of 5 V. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports an input voltage up to 6 V. Key electrical parameters include a quiescent current of 1.5 mA and a shutdown current of less than 1 µA. It features a 1.6 MHz fixed switching frequency and offers a signal-to-noise ratio of 95 dB. The amplifier is housed in a compact 20-UQFN package measuring 3x3 mm.

Feature Summary

• Class-D topology provides high efficiency suitable for battery-powered applications
• Integrated LC filter eliminates the need for external output capacitors
• Low quiescent current extends battery life in portable devices
• Built-in thermal protection safeguards against overheating

Applications

• Mobile phones
• Portable media players
• Bluetooth speakers

Procurement Notes

Verify the specific suffix 'MUTXG' to ensure the correct 20-UQFN package and tape-and-reel quantity. Confirm RoHS compliance status through official onsemi documentation prior to integration. Check for any recent Product Change Notifications (PCN) or End-of-Life announcements, as component availability may vary. Ensure the supplier provides valid traceability documents matching the manufacturer's part number.

Selection Notes

Select this component when a cost-effective mono amplifier is required for space-constrained portable electronics. The 1.2 W output power is sufficient for small form-factor speakers. Consider the 20-UQFN footprint for PCB layout compatibility. Verify that the application does not require stereo output, as this is a single-channel device. Evaluate the fixed switching frequency against potential EMI constraints in the design.

Part Context

The NCP2830 belongs to onsemi's portfolio of audio amplifiers tailored for mobile communications. It complements other Class-D solutions by offering a balance of performance and simplicity. The UQFN package aligns with industry trends toward miniaturization in handheld devices. This series targets OEMs seeking reliable audio performance without complex external filtering requirements.
