ZXCW6100S28TC

Overview

The ZXCW6100S28TC is a 24-bit stereo direct drive digital audio amplifier from Diodes Incorporated. It operates on a 3.3V supply with an operating temperature range of -40°C to +85°C and is housed in a 28-pin SSOP package. The device supports sampling rates up to 192kHz, featuring a typical dynamic range of 101dB and a noise floor of -110dB. It includes a 3-wire SPI interface for control, digital volume adjustment from -94.5dB to +25dB, and bass/treble controls.

Feature Summary

• Integrates a complete digital audio interface from data input to loudspeaker output using direct drive PWM technology.
• Supports multiple digital audio formats including I2S, Left Justify, and Right Justify with variable bit depths.
• Includes proprietary NOVALOAD™ overload management to prevent clipping by adjusting gain dynamically.
• Offers user-definable digital volume, mute, bass, and treble controls via a bi-directional SPI interface.

Applications

• 5.1 Integrated DVD amplifiers
• Home theatre systems
• Mini Hi-fi systems
• Automotive audio
• PC audio

Procurement Notes

Verify the specific suffix 'TC' against official documentation to confirm tape and reel packaging or temperature grade variations. Ensure the source component matches the 28-pin SSOP form factor and 3.3V logic requirements. Confirm RoHS compliance status through the manufacturer's current datasheet revision.

Selection Notes

Select this component for applications requiring high-fidelity digital audio amplification with minimal external components. Consider the 3.3V supply constraint and the need for an external MOSFET H-bridge stage. Evaluate the SPI interface compatibility with the host controller for configuration and real-time control needs.

Part Context

This part belongs to the Acoustar™ range of digital audio power devices. It represents a solution designed to replace traditional analog amplification stages with a fully digital approach, reducing component count while maintaining high performance metrics suitable for consumer electronics.

Replacement Considerations

Check for updated revisions within the ZXCW6100 series. Verify pinout compatibility if substituting with other stereo digital amplifiers. Ensure the replacement supports the required 192kHz sampling rate and 24-bit resolution.

FAQ

What digital audio input formats are supported?

The device supports 24-bit I2S, 24-bit Left Justify, and 16/24-bit Right Justify formats.

How is the device controlled?

Function control is achieved via a 3-wire bi-directional SPI interface using 8-bit control and 64-bit data strings written to internal registers.
