NCP4894DMR2G

Overview

The NCP4894DMR2G is a differential audio power amplifier designed for portable communication devices. It delivers 1.0 W to an 8 Ω load from a 5.0 V supply with less than 0.01% distortion. The device operates on a 2.2 V to 5.5 V supply and features selectable shutdown logic, pop-and-click noise protection, and thermal overload protection. It utilizes a Micro-10 package.

Feature Summary

Differential amplification architecture eliminates the need for output coupling capacitors
Selectable shutdown mode allows configuration via high or low logic signals
Integrated circuitry prevents audible pop and click noises during transitions
High power supply rejection ratio enables direct battery connection

Applications

Portable electronic devices
Personal digital assistants (PDAs)
Mobile phones

Procurement Notes

Verify the specific suffix 'DMR2G' corresponds to the Micro-10 package and lead-free status. Confirm the datasheet revision matches design requirements. Ensure PCB assembly processes align with lead-free soldering specifications for this variant. Validate pinout compatibility with existing layouts before finalizing procurement.

Selection Notes

Select this component for applications requiring high-quality audio in space-constrained portable devices. The differential output reduces external component count compared to single-ended designs. Consider the Micro-10 package dimensions for board real estate constraints. Verify that the required gain settings and bypass capacitor values meet the desired turn-on time specifications.

Part Context

This part belongs to the NCP4894 family of 1.8 Watt differential audio power amplifiers. Other variants include the 9-Pin Flip-Chip and DFN10 packages. The family is optimized for mobile phone applications, providing superior PSRR and low current consumption in shutdown mode while maintaining high audio fidelity.
