NCP2820AFCT2G

Overview

The NCP2820AFCT2G is a mono Class-D audio power amplifier from onsemi. It delivers 2.65 W continuous average power to a 4.0 Ω load and 1.4 W to an 8.0 Ω load at 5.0 V supply with THD+N < 1%. The device operates within a 2.5 V to 5.5 V range, features a 9-pin flip-chip CSP package, and includes a 300 kΩ internal shutdown resistor.

Feature Summary

• Filterless capability for inductive transducers
• Fully differential input design
• Advanced pop and click noise protection
• External gain configuration

Applications

• Cellular handsets
• PDAs
• Portable electronic devices

Procurement Notes

Verify the specific suffix 'FC' corresponds to the 9-pin flip-chip CSP package (CASE 499AL) as defined in the datasheet ordering information. Confirm that the component meets lead-free requirements and check for any automotive-specific variants if unique site control is required.

Selection Notes

Select this part for applications requiring high efficiency up to 90% and low quiescent current. The fully differential input eliminates the need for input coupling capacitors. Ensure the total equivalent capacitance at the output remains below 150 pF for optimal sound quality.

Part Context

This component belongs to the NCP2820 series of filterless Class-D amplifiers. It utilizes pulse width modulation to process analog inputs, offering space savings by removing output filters. The series supports various packages including UDFN8 and flip-chip CSP.

Replacement Considerations

The NCP2820A variant offers faster start-up times. Other series members include NCP2820MUTBG and NCV2820MUTBG.
