DS2130+

Overview

The DS2130+ is a single-chip ADPCM codec manufactured by Analog Devices Inc./Maxim Integrated. It supports both A-law and μ-law compression algorithms for voice signal processing. The device operates within a supply voltage range of 4.75 V to 5.25 V and functions reliably across an industrial temperature range of -40°C to +85°C. It utilizes a 28-pin Plastic Quad Flat Pack (PQCC) package with LCC-28 footprint. Key electrical characteristics include a typical operating current of 60 mA at 5 V. The component integrates necessary filters and clock generation circuits for standalone operation in digital telephony applications.

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm temperature grade and packaging variant. Ensure compatibility with existing board layouts regarding the PQCC-28 pinout. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Cross-reference lead times and availability directly with authorized distributors rather than relying on general market indicators.

Selection Notes

Select this component when designing systems requiring standardized ADPCM processing with minimal external passive components. Evaluate power consumption requirements against the specified 60 mA typical draw at 5 V. Consider the thermal performance within the -40°C to +85°C range for the intended enclosure environment. Verify that the host microcontroller supports the required serial interface timing for data exchange.

Part Context

The DS2130+ belongs to the broader family of Maxim Integrated voice codecs designed for digital communication networks. It serves as a foundational building block for converting analog voice signals into compressed digital formats for transmission. This series is widely recognized in legacy and modern telecom infrastructure for its reliability and standardized protocol support.

Replacement Considerations

Consult official substitution guides for direct pin-compatible alternatives such as the DS2130Q or DS2130E. Verify functional equivalence regarding algorithm support and interface timing before implementation.
