Procurement Notes

Verify the current manufacturing status as this specific part number may be discontinued or superseded by newer revisions. Confirm that the 16-QSOP-EP package with exposed pad matches your PCB footprint requirements. Ensure compatibility with external Zetex HDMOS MOSFETs if utilizing reference designs. Check RoHS3 compliance documentation for environmental regulations.

Selection Notes

Select this controller when designing stereo Class D amplifiers requiring precise oscillator frequency matching via external components. It is suitable for applications needing high gate drive capability to support external bridge MOSFETs. Consider the exposed pad thermal management requirements for the QSOP-EP package. Verify that the 12V to 18V operating voltage range aligns with your system power supply design.

Part Context

This component belongs to the ZXCD1010 family of high-fidelity Class D audio amplifier controllers. It serves as an enhanced version of the ZXCD1000, offering improved accuracy through external oscillator timing.
