NCP2811AMTTXG

Overview

The NCP2811AMTTXG is a Class-AB stereo audio amplifier manufactured by onsemi. It operates from a single power supply ranging from 2.7 V to 5 V and delivers 60 mW into a 32 Ω load or 110 mW into a 16 Ω load. The device features low total harmonic distortion plus noise, ensuring high-fidelity audio reproduction. It is housed in a compact TSSOP-14 package suitable for surface mount applications. The amplifier supports single-ended input signals and functions within an operating temperature range of -40 °C to +125 °C.

Feature Summary

Class-AB topology for efficient audio amplification with reduced crossover distortion
Single-supply operation compatible with standard battery-powered voltage levels
Compact TSSOP-14 package designed for space-constrained mobile designs

Applications

Mobile phones
MP3 players

Procurement Notes

Verify the specific suffix 'AMTTXG' against official onsemi documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status via the manufacturer's datasheet. Ensure the component meets the required thermal management standards for the intended application environment before finalizing procurement.

Selection Notes

Select this component for portable audio devices requiring a balance between output power and package size. The single-supply capability simplifies power design compared to dual-rail solutions. Verify that the 14-pin TSSOP footprint aligns with the PCB layout constraints and that the thermal performance is adequate for the expected duty cycle.
