AD976BRZ

The AD976BRZ is a 16-bit successive-approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices, engineered for precision data acquisition systems that require high accuracy and low power consumption from a single 5 V supply. This device belongs to the AD976/AD976A family and delivers 16-bit resolution with no missing codes, featuring a parallel interface for straightforward integration with microcontrollers and digital signal processors. The “B” grade offers enhanced linearity performance, while the overall architecture achieves a 100 kSPS throughput rate, making it suitable for digitizing low-frequency sensor signals, transducer outputs, and industrial process variables. Its on-chip reference and clock simplify design, reducing external component count in space-constrained analog front ends.

Typical applications span industrial automation, test and measurement instrumentation, medical diagnostic equipment, and high-reliability military/aerospace subsystems where consistent performance over temperature is critical. The BRZ suffix designates an industrial operating range of –40°C to +85°C in an RoHS-compliant 28-lead SOIC package. Procurement specialists should note that this is a mature, commercially oriented part; it is not inherently qualified to full military screening standards such as MIL-PRF-38535 unless a compliant suffix (e.g., /883B) is specified. While still actively supported by Analog Devices, design-in teams should verify long-term availability and product lifecycle status, especially for programs with extended production or sustainment requirements. The AD976BRZ remains a reliable workhorse for high-resolution, single-supply conversion, but prudent obsolescence planning and authorized distribution sourcing are recommended for critical infrastructure and defense procurement.
