AD977BNZ

Analog To Digital Converters (ADC) Overview

The AD977BNZ is a monolithic 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes successive approximation register (SAR) architecture and operates on a single +5 V supply. The device features a serial interface for data output and supports sampling rates up to 100 kSPS. It is housed in a 20-lead plastic dual in-line package (PDIP). Key electrical specifications include a signal-to-noise ratio of 85 dB, differential nonlinearity of -1 LSB/1.75 LSB, integral nonlinearity of +/- 2 LSB, and gain error of +/- 0.25% FSR. The component is designed for industrial temperature ranges from -40°C to +85°C with a maximum power dissipation of 100 mW.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 16-bit SAR ADC core with a serial output interface to minimize digital noise coupling and simplify system interconnects.
• Supports both external and internal reference voltage configurations, allowing flexibility in precision applications requiring stable conversion baselines.
• Operates efficiently on a single +5 V power supply, reducing system complexity and eliminating the need for negative voltage rails.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Portable instrumentation utilizing battery-powered single-supply architectures
• Medical equipment demanding low power consumption and high accuracy

Analog To Digital Converters (ADC) Procurement Notes

Verify authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific lot traceability requirements before finalizing orders. Check for obsolescence notices as this part may be subject to restricted production runs. Ensure storage conditions meet humidity sensitivity levels to prevent package degradation prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select the AD977BNZ when a 16-bit resolution and 100 kSPS throughput are required in a through-hole DIP package. Compare against the AD977CRZ if surface mount technology is preferred for PCB layout constraints. Evaluate the AD977AANZ if a higher sampling rate of 200 kSPS is necessary for faster data capture needs. Consider power dissipation limits relative to ambient thermal conditions in enclosed enclosures.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD977 series of monolithic ADCs from Analog Devices. The series includes variants such as the AD977AANZ and AD977CNZ, which share similar architectural foundations but differ in sampling speeds and package types. The AD977BNZ specifically addresses applications needing robust through-hole mounting options alongside precise 16-bit conversion capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

The AD977CRZ serves as a surface-mount equivalent within the same family. For higher speed requirements, the AD977AANZ offers 200 kSPS performance. Verify pin compatibility and software driver support when transitioning between these specific model numbers.
