ML22Q244-NNNTDZWATL

Audio Special Purpose Overview

The ML22Q244-NNNTDZWATL is a speech synthesis LSI from the ROHM LAPIS ML22Q series, designed for short-time playback applications. It integrates an internal D-class speaker amplifier, allowing for a single-chip audio solution. The device utilizes HQ-ADPCM compression algorithms for high-quality voice output and features a clock-synchronous serial interface for data input.

Audio Special Purpose Feature Summary

• Speech Synthesis LSI with Internal D-Class Speaker Amplifier
• High-Quality Audio via HQ-ADPCM Compression
• Clock-Synchronous Serial Interface (SP)
• Single-Chip Solution: Integrates Memory, DAC, and Amplifier
• Operating Temperature Range: -40°C to +105°C (Industrial Grade)

Audio Special Purpose Applications

• Short-duration voice guidance systems
• Audio signaling devices
• Embedded voice modules in consumer electronics
• Industrial control panels requiring voice feedback

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix NNNTDZWATL against official ROHM documentation to confirm package type (TSSOP) and tape/reel specifications. Ensure compatibility with the host microcontroller's clock-synchronous serial interface protocol. Confirm that the internal memory capacity meets the specific audio data length requirements of the application.

Audio Special Purpose Selection Notes

Select this component when a compact, single-channel audio processor with integrated amplification is required for short-duration playback. The ML22Q series offers a balance between processing capability and physical size through its TSSOP packaging. Verify if the internal memory capacity meets the specific audio data length requirements of the application.
