NCS2211DR2G

Overview

The NCS2211DR2G is a Class-AB audio power amplifier manufactured by onsemi, designed for single-supply operation within a voltage range of 2.7 V to 5.5 V. It features a differential input and delivers up to 1.5 W of output power into an 8-ohm load. The device incorporates a shutdown mode to minimize current consumption during standby periods. Key electrical specifications include a gain-bandwidth product of 12 MHz, a total harmonic distortion plus noise of 0.2%, and a quiescent operating current of 20 mA. It supports an output current of 500 mA and operates reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Class-AB topology providing high-fidelity audio amplification with low distortion characteristics.
• Differential input configuration enabling robust noise rejection in signal paths.
• Integrated shutdown mode functionality to significantly reduce power consumption when inactive.

Applications

• Speaker systems requiring efficient mono audio amplification
• Portable electronic devices utilizing single-supply battery power
• Audio circuits demanding low total harmonic distortion

Procurement Notes

Verify the specific suffix DR2G corresponds to the SOIC-8 tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your manufacturing region. Ensure the ordering quantity aligns with the standard factory pack size of 2500 units or available cut-tape options. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component for applications necessitating a single-channel mono amplifier with differential inputs. It is suitable for designs constrained by low supply voltages starting at 2.7 V. Consider the 12 MHz gain-bandwidth product for adequate audio frequency response. Evaluate the thermal performance within the specified -40°C to +85°C operational range to ensure reliability under varying environmental conditions without requiring additional heat sinking.
