NCP2811BDTBR2G

Overview

The NCP2811BDTBR2G is a Class AB stereo audio power amplifier manufactured by onsemi. It operates from a single supply voltage ranging from 2.7 V to 5 V and delivers a maximum output power of 0.06 W into a 32 Ω load or 0.11 W into a 16 Ω load. The device features two channels, utilizes a TSSOP-14 package with dimensions of 5.1 x 4.5 x 1.05 mm, and supports a bandwidth up to 20 kHz. It functions within an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Stereo audio amplification in a compact surface-mount package
• Operates from a single low-voltage power supply
• Designed for mobile and portable multimedia applications

Applications

• Mobile phones
• MP3 players

Procurement Notes

Verify the specific suffix 'R2G' against the manufacturer's current datasheet to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout. Cross-reference the component marking code with official documentation to prevent counterfeit substitution during assembly.

Selection Notes

Select this component for designs requiring dual-channel audio output from a single IC. It is suitable for battery-powered systems due to its wide single-supply voltage range. Consider the TSSOP-14 package size when determining board space constraints. Verify that the thermal dissipation requirements for the intended load impedance are met by the enclosure type.

Part Context

This device belongs to onsemi's portfolio of audio amplifiers designed for consumer electronics. It provides a solution for stereo sound reproduction in space-constrained mobile devices. The product line focuses on balancing audio performance with power efficiency for portable applications.

Replacement Considerations

Consult the manufacturer's official cross-reference list for verified substitutes. Ensure any replacement maintains the same TSSOP-14 footprint and compatible supply voltage range.
