NCP2824FCT2G

Overview

The NCP2824FCT2G is a single-channel Class D audio power amplifier IC from onsemi, designed for portable consumer electronics. It delivers 1.5 W into an 8 Ω load and 2.4 W into a 4 Ω load. The device operates within a supply voltage range of 2.5 V to 5.5 V. It integrates Auto Gain Control (AGC) functionality to manage output levels. The component is housed in a compact 9-pin WCSP package with dimensions of 1.45 x 1.45 mm.

Feature Summary

• Single-channel Class D architecture optimized for mono audio applications
• Integrated Auto Gain Control (AGC) for dynamic level management
• Ultra-compact 9-pin WCSP packaging suitable for space-constrained designs

Applications

• Portable audio devices
• Consumer electronics with limited board space
• Mono audio systems requiring integrated gain control

Procurement Notes

Verify the specific suffix 'FCT2G' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Ensure compatibility with the intended supply voltage range of 2.5 V to 5.5 V. Confirm that the 9-pin WCSP package matches the PCB footprint requirements. Check for any recent lifecycle status updates or obsolescence notices from onsemi before finalizing procurement plans.

Selection Notes

Select this component when a single-channel Class D amplifier with built-in AGC is required for portable applications. It is suitable for designs needing high efficiency in a minimal footprint. Consider the 1.45 x 1.45 mm WCSP package for tight spatial constraints. Verify that the target load impedance (4 Ω or 8 Ω) aligns with the desired output power specifications of 2.4 W or 1.5 W respectively.

Part Context

The NCP2824FCT2G belongs to onsemi's portfolio of audio power amplifiers tailored for mobile and handheld devices. It represents a solution for integrating high-efficiency amplification without external gain adjustment components. The WCSP package technology allows for reduced board area compared to traditional packages, supporting the miniaturization trends in modern consumer electronics.
