Overview
The IS31AP2006-DLS2-TR is a mono Class-D audio power amplifier in a DFN-8 package. It delivers 3W into 4Ω and 1.7W into 8Ω at 5V with 10% THD+N. Operating on a 2.7V to 5.5V supply, it features a filter-less PWM architecture, fully differential design, and integrated pop-and-click suppression. The device operates within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Filter-less PWM architecture eliminates the need for external LC output filters
- Fully differential design reduces RF rectification and removes bypass capacitor requirements
- Integrated pop-and-click suppression circuitry minimizes audible noise during startup and shutdown
Applications
- Wireless or cellular handsets
- Portable DVD players
- Notebook PCs
- USB speakers
Procurement Notes
Verify the specific ordering suffix DLS2-TR against the manufacturer's current datasheet to confirm package type and reel quantity specifications. Ensure the component meets RoHS and Halogen-Free compliance requirements for your target assembly process. Confirm that the industrial temperature rating aligns with your system's operational environment constraints.
Selection Notes
Select this component for applications requiring high efficiency and minimal external components. The fully differential input allows for flexible gain configuration and signal summing from multiple sources. Consider the DFN-8 package size for space-constrained portable designs where thermal dissipation can be managed via the exposed pad.
Part Context
This part belongs to the IS31AP2006 series of high-efficiency Class-D amplifiers. It is designed to replace traditional Class-AB amplifiers in portable electronics by offering superior power efficiency and reduced system cost through the elimination of bulky output filters.
