AD976BRS

Analog To Digital Converters (ADC) Overview

The AD976BRS is a 16-bit, 100 kSPS successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It operates from a single +5 V supply and dissipates a maximum of 100 mW. The device features a parallel interface, an internal 2.5 V reference, and on-chip clocking. Key electrical specifications include a throughput rate of 100 kSPS, a signal-to-noise plus distortion ratio (S/(N+D)) of 85 dB, and integral nonlinearity error of ±3 LSB. The analog input range is ±10 V with an impedance of 23 kΩ. It is housed in a 28-lead Shrink Small Outline Package (SSOP).

Analog To Digital Converters (ADC) Feature Summary

• High-speed 16-bit resolution with 100 kSPS throughput.
• Single +5 V supply operation for simplified power design.
• Integrated 2.5 V reference and on-chip clock generation.
• Factory calibrated for high linearity and low noise performance.

Analog To Digital Converters (ADC) Applications

• Industrial data acquisition systems requiring precise measurement.
• Process control applications utilizing standard industrial voltage ranges.
• General-purpose instrumentation and test equipment.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade (A, B, or C) required for your application, as performance metrics like S/(N+D) vary between grades. Confirm package availability, as the SSOP variant may have limited stock compared to DIP or SOIC options. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select the AD976BRS when a 100 kSPS sampling rate is sufficient for the application. Choose this part over the AD976A series if lower power consumption at reduced speed is prioritized. Ensure the system can accommodate the ±10 V input range or implement appropriate scaling circuitry if different input levels are needed.

Analog To Digital Converters (ADC) Part Context

The AD976BRS belongs to the AD976/AD976A family of BiCMOS A/D converters. This family offers a complete 16-bit solution integrating the ADC, reference, and clock. The 'B' designation indicates a specific performance grade with 85 dB S/(N+D), while 'RS' denotes the 28-lead shrink small outline package.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same package and pinout include other grades of the AD976BRS (e.g., AD976ARS or AD976CRS) depending on required linearity and noise specifications. Cross-family replacements like the AD976A series offer higher speeds but require verification of timing and power constraints.
