Functional safety requirements are often seen as a mere checkbox in the design process, but at Analog Devices, Inc. (ADI), we see them as a differentiator—a way to add value for our customers and their end users by making products safer. Thousands of ADI products come out of the box ready to satisfy functional safety standards such as ASIL compliance, so you never have to make the choice between safety and scalability.
ADI is a leading supplier of micro-electromechanical systems (MEMS) based airbag sensors, ADCs, and DACs for PLC analog input/output cards in safety applications. Enhanced IEC 61508 and ISO 26262 development processes further refine ADI’s solutions capability and robustness for functional safety applications.
Functional safety standards dictate three key requirements for integrated circuits (ICs).
Reliability – ADI is committed to delivering products that meet the highest levels of reliability.
Diagnostics – ADI leverages leading-edge sensing and advanced diagnostics to detect failures, random or systematic.
Quality Management – ADI has developed processes and quality management systems for industrial and automotive functional safety.
Diagnostics
Whether your metric is safe failure fraction (SFF) or single point fault (SPF), ADI will collaborate with you to meet your safety goals. As a leading supplier of mixed-signal, MEMS, and DSP products, ADI has experience in a wide variety of diagnostic techniques including the use of hardware cyclic redundancy check (CRC) to protect serial peripheral interface (SPI) systems; fuses and flash memory; electrostatic self-test for MEMS; and error correcting codes (ECC) to detect soft errors in RAMs.
Applicable IC Development Standards
IEC 61508: ADI has developed a safety process and implemented a corporate framework consistent with the requirements of IEC 61508.
ISO 26262: ISO 26262 sets out the functional safety requirements for the automotive sector. ADI has developed a safety process and implemented a corporate framework consistent with the requirements of ISO26262.
Industrial Functional Safety Solutions
At Analog Devices, our commitment to our customers includes a thorough product development process, an established zero-defect culture, and in-house industry-certified functional safety domain experts to help you build products that meet relevant certification standards.
Integrated Circuits Functional Safety
Integrated circuits (ICs) are at the root of all modern safety systems, largely because advanced integration can simplify system-level implementation and improve reliability. For more information on functional safety techniques, please refer our Safety Matters blog series.
Failure Rate Data
ADI publishes failure-in-time (FIT) data for its products based on accelerated life testing. Our online reliability tool can be used to generate an expected FIT rate for a specific product or based on the process node, e.g., 0.18μm CMOS. The tool generates data on confidence levels of 60% and 90% and allows the average operating temperature to be selected.
ADI also has the capability to predict failure rates using IEC 62380, SN29500, and other industry standards.
