DS2130

Overview

The DS2130 is a voice recording and playback integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It supports serial interfaces for data transfer and provides audio durations ranging from 8 to 32 seconds. The device features a filter pass band of 1.7kHz, optimized for voice frequency applications. It is housed in a 28-DIP package, suitable for through-hole mounting in telecommunications and industrial control systems requiring dedicated voice storage capabilities.

Feature Summary

• Integrated voice recording and playback functionality
• Serial interface support for digital data handling
• Optimized 1.7kHz filter pass band for voice clarity

Applications

• Telecommunications equipment
• Industrial control systems
• Voice messaging devices

Procurement Notes

Verify component authenticity due to obsolete status. Check datasheet revisions for pinout compatibility. Confirm package integrity upon receipt. Validate serial interface timing requirements against system specifications. Ensure proper handling procedures are followed during installation.

Selection Notes

Consider the 8 to 32-second duration range when evaluating memory needs. Assess the 1.7kHz bandwidth suitability for specific voice quality requirements. Verify serial interface compatibility with existing microcontrollers. Evaluate the 28-DIP package constraints for PCB layout design.

Part Context

This component belongs to the voice processing family from Maxim Integrated, now part of Analog Devices. It serves as a specialized solution for embedded voice applications, distinct from general-purpose memory or audio codecs. The DS2130 represents an older generation technology focused on simple, reliable voice storage.

Replacement Considerations

No public confirmed substitute part numbers are available. The component status is obsolete. Designers should evaluate newer voice recording ICs or external memory solutions with appropriate controllers for modern replacements.
