AD42/173-0

Overview

The AD42/173-0 is a 16-bit Analog-to-Digital Converter (ADC) integrated circuit manufactured by Analog Devices Inc. It is designed for applications requiring high-resolution data conversion. The component operates with a limited analog input common-mode range, typically spanning from 0 to VREF. It lacks galvanic isolation capabilities, which necessitates careful system design in environments with significant ground offsets exceeding ±1V to ensure accurate signal processing and prevent measurement errors.

Feature Summary

• Provides 16-bit resolution for precise analog signal digitization
• Operates within a standard single-supply common-mode input range relative to reference voltage
• Designed for general-purpose data acquisition without built-in isolation

Applications

• High-resolution data acquisition systems
• Precision instrumentation where ground offsets are minimal
• Industrial control interfaces requiring 16-bit accuracy

Procurement Notes

Verify the specific suffix and revision code against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the supply chain source provides valid traceability for this specialized ADC. Confirm that the application environment does not exceed the specified common-mode input limits or require isolation, as the device lacks these features.

Selection Notes

Select this component only when 16-bit resolution is required and the system ground potential remains stable within the specified common-mode range. Do not use if galvanic isolation is necessary or if ground offsets exceed ±1V. Evaluate power consumption requirements against other low-power ISO ADC options if isolation is eventually needed.

Part Context

This part belongs to the Analog Devices family of precision data converters. It serves as a specialized solution for applications demanding high bit-depth conversion without the complexity or cost of isolated architectures. It complements other ADI components in mixed-signal system designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative 16-bit ADCs based on specific interface and performance requirements.
