DS2132AN

Overview

The DS2132AN is a single-channel voice recording and playback integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V and supports serial interfaces for data transmission. The device accepts analog single-ended and Pulse Code Modulation (PCM) input signals, processing them for storage or playback. It features built-in automatic gain control and DTMF transceiver capabilities to manage signal levels and tone detection. Designed for industrial reliability, the component functions effectively across an operating temperature range of 0°C to 70°C. It is housed in a 28-pin Dual In-line Package (DIP) with a standard width of 0.600 inches, facilitating through-hole mounting on printed circuit boards.

Feature Summary

• Integrates automatic gain control for dynamic signal level management
• Includes DTMF transceiver functionality for tone detection and generation
• Supports serial interface communication for system integration
• Handles both analog single-ended and PCM signal formats

Applications

• Automated message systems requiring voice storage and retrieval
• Telecommunications equipment utilizing DTMF signaling
• Industrial voice recording modules
• Playback devices for pre-recorded announcements

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to end-of-life status. Confirm package integrity and pin alignment against the 28-DIP specification before installation. Review datasheet revisions for any historical manufacturing changes that may affect compatibility with existing designs.

Selection Notes

Select this component when a dedicated single-channel voice solution with integrated DTMF handling is required. Ensure the design environment accommodates the 4.5 V to 5.5 V power supply range. Consider the 28-DIP footprint constraints during PCB layout planning. Evaluate thermal requirements against the 0°C to 70°C operational limit.

Part Context

The DS2132AN belongs to the DS2132 family of voice recording and playback ICs from Maxim Integrated. This series provides specialized solutions for telephony and voice messaging applications. The 'N' suffix typically denotes the DIP package variant, distinguishing it from surface-mount options like the SOIC version. It serves as a core component for systems needing compact voice data handling without external microcontrollers.

Replacement Considerations

The DS2132A is listed as obsolete. Potential replacements include other single-channel voice ICs from Analog Devices or third-party manufacturers offering similar serial interfaces and DTMF capabilities. Verify pinout compatibility and electrical specifications before substitution.
