ZXCD1210JB16TA

Overview

The ZXCD1210JB16TA is a high-performance analog input Class D modulator manufactured by Diodes Incorporated. It provides complete control and modulation functions for high-efficiency audio amplifier solutions. The device operates with a supply voltage range of 12V to 18V and features an internal oscillator set to approximately 200kHz via an external capacitor. Packaged in a 16-QFN (4x4mm) format, it supports open-loop and closed-loop architectures to achieve low distortion and high dynamic range.

Feature Summary

• Output power capability up to 500W into 4Ω with THD+N <0.05% and dynamic range of 98dB
• Frequency response flat within ±0.5dB from 20Hz to 20kHz for full-band applications
• Integrated on-chip series regulators dropping VCC to 9V and 5.5V supplies
• QFN16 4x4 package design for compact footprint

Applications

• Subwoofers
• Home theatre systems
• Multimedia audio
• Wireless speakers
• Portable audio devices

Procurement Notes

Verify the specific ordering suffix 'JB16' against current manufacturer documentation to confirm tape and reel quantities and packaging details. Ensure compatibility with existing thermal management designs given the QFN16 exposed pad requirement. Confirm availability status as product lifecycles may change.

Selection Notes

Select this component for Class D amplifier designs requiring analog input modulation. Ensure the external clock capacitor is rated correctly to maintain the ~200kHz frequency. Consider closed-loop reference designs for subwoofer applications requiring high damping factors and supply rejection, or open-loop designs for cost-effective full-bandwidth implementations.

Part Context

Originally developed by Zetex Semiconductors plc, this component is part of the ZXCD series of Class D modulators. Diodes Incorporated acquired Zetex, integrating these products into their portfolio. The ZXCD1210 serves as the core modulation engine for various Zetex reference designs, including the ZXCDSUBEV series for subwoofers and stereo/mono evaluation boards.
