AD976AN

Analog To Digital Converters (ADC) Overview

The AD976AN is a 16-bit, 100 kSPS analog-to-digital converter (ADC) manufactured by Analog Devices. It operates from a single +5 V supply and dissipates a maximum of 100 mW. The device features a switched capacitor successive approximation architecture with an internal 2.5 V reference and on-chip clock. It accepts a bipolar ±10 V analog input range through a high-speed parallel interface. The component is housed in a 28-lead skinny DIP package and is specified for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Single-supply operation with low power consumption
• Integrated 2.5 V reference and on-chip clock
• Factory calibrated for minimized linearity errors
• High-speed parallel data output interface

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data acquisition modules
• Portable instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade (A, B, or C) required for your application, as performance metrics like Signal-to-(Noise+Distortion) vary by grade. Confirm the package type matches the design footprint. Check current availability status as older components may have limited stock or end-of-life implications.

Analog To Digital Converters (ADC) Selection Notes

Select the AD976AN when a 100 kSPS throughput rate is sufficient for the application. Choose this part over the AD976AAN if lower speed requirements allow for potential cost savings or if the specific timing characteristics of the 100 kSPS model are preferred. Ensure the ±10 V input range aligns with the sensor signal levels.

Analog To Digital Converters (ADC) Part Context

The AD976AN belongs to the AD976/AD976A family of BiCMOS ADCs. It shares the same pinout and core architecture as the faster AD976AAN but is optimized for 100 kSPS throughput. Both variants utilize the same 28-lead Skinny DIP, SSOP, and SOIC packages and offer identical power and reference integration features.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include the AD976BN and AD976CN, which share the 100 kSPS throughput but differ in AC accuracy grades. For higher speed requirements, the AD976AAN series serves as the performance upgrade path.
