AD976ABRZ

Analog To Digital Converters (ADC) Overview

The AD976ABRZ is a high-speed, low-power 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes a successive approximation register (SAR) architecture with a switched-capacitor design and operates from a single 5 V supply. The device features a throughput rate of 200 kSPS and accepts a single-ended analog input range of ±10 V. Key electrical specifications include a signal-to-noise ratio (SNR) of 85 dB, differential nonlinearity (DNL) of ±1 LSB or 1.75 LSB, integral nonlinearity (INL) of ±2 LSB, and a gain error of ±0.25% FSR. Power dissipation is limited to 100 mW maximum. The component is housed in a 28-lead SOIC package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a factory-calibrated 16-bit SAR ADC with on-chip clock generation for simplified system design.
• Provides high-speed parallel interface compatible with standard digital logic families.
• Offers flexibility through selectable external or internal 2.5 V voltage reference options.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise data acquisition.
• Medical instrumentation and diagnostic equipment.
• Test and measurement instruments such as oscilloscopes and analyzers.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BRZ' against the manufacturer's official documentation to confirm package type and lead-free compliance status. Ensure that the required throughput and linearity specifications align with the application requirements before procurement. Confirm availability status directly with authorized distributors as supply levels may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 200 kSPS sampling rate are required within a single 5 V supply constraint. Compare DNL and INL specifications against system accuracy needs. Consider the SOIC package dimensions for PCB layout compatibility. Evaluate power consumption limits relative to thermal management capabilities in the target enclosure.

Analog To Digital Converters (ADC) Part Context

The AD976ABRZ belongs to the AD976 family of BiCMOS A/D converters. This series includes variants with different throughput rates, such as the 100 kSPS AD976. The family is characterized by its combination of high speed, low power consumption, and integrated reference circuitry, making it suitable for applications demanding reliable performance in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The AD976ABNZ serves as a pin-compatible alternative offering the same electrical specifications but in a PDIP package. Verify package footprint differences if board space allows for through-hole mounting instead of surface mount technology.
