DS2450S+

Analog To Digital Converters (ADC) Overview

The DS2450S+ is a 1-Wire Quad A/D Converter based on a successive-approximation architecture with a four-to-one analog multiplexer. It features four high-impedance inputs for measuring analog voltages over the 1-Wire bus, supporting user-programmable input ranges of 2.56V or 5.12V and resolutions from 1 to 16 bits. The device operates on a single 5V supply, consuming 2.5 mW active power and 25 μW idle power. It includes built-in multidrop controller capabilities, alarm thresholds, and open-drain digital outputs. Communication occurs at up to 16.3 kbps normally, boosting to 142 kbps in Overdrive mode. It utilizes a unique 64-bit factory-lasered registration number and CRC protection.

Analog To Digital Converters (ADC) Feature Summary

• Four high-impedance analog inputs with programmable voltage ranges and resolution settings
• Built-in multidrop controller enabling identification and operation of multiple devices on a common 1-Wire bus
• Channels not used as analog inputs can function as open-drain digital outputs for closed-loop control
• On-chip 16-bit CRC generator safeguards data transfers against transmission errors

Analog To Digital Converters (ADC) Applications

• Multidrop sensor networks requiring analog voltage measurement
• Closed-loop control systems utilizing digital output channels
• Applications necessitating absolute traceability via unique factory-lasered registration numbers

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel availability. Confirm lead-free compliance status indicated by the plus sign. Ensure the selected variant matches the required surface-mount packaging specifications for the target assembly process.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-wire interface is required for quad-channel analog conversion. Consider the 16.3 kbps standard speed versus 142 kbps Overdrive mode based on system latency requirements. Verify that the 5V single-supply operation aligns with the available power infrastructure.

Analog To Digital Converters (ADC) Part Context

The DS2450S+ belongs to the DS2450 family of 1-Wire Quad A/D Converters manufactured by Analog Devices Inc./Maxim Integrated. It shares the core functional architecture with other variants in the series, differentiated primarily by packaging options such as SOIC and tape-and-reel configurations.

Analog To Digital Converters (ADC) Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify pin compatibility and electrical specifications before substituting.
