AD977ACNZ

Analog To Digital Converters (ADC) Overview

The AD977ACNZ is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It features a single-ended input architecture and operates from a single 5 V supply with a maximum power dissipation of 100 mW. The device supports a throughput rate of 200 kSPS and includes an internal 2.5 V reference. It utilizes a high-speed serial interface for data output and is housed in a 20-lead SOIC package. The component is specified for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Factory calibrated switched capacitor architecture minimizes linearity errors
• Single 5 V supply operation reduces system complexity
• Internal 2.5 V voltage reference eliminates external components
• High-speed serial interface simplifies digital connection

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring 16-bit resolution
• Data acquisition modules for sensor interfacing
• Battery-powered instrumentation due to low power consumption

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CNZ' indicates the commercial temperature grade and lead-free RoHS compliant packaging. Confirm availability status as distribution channels may list limited stock or obsolete status for this specific variant. Ensure the ordering information matches the required 200 kSPS speed grade, distinct from the standard AD977 model.

Analog To Digital Converters (ADC) Selection Notes

Select the AD977ACNZ when a 200 kSPS sampling rate is required, distinguishing it from the slower AD977 variant. Choose this part for applications needing a single 5 V supply and integrated reference. Verify that the single-ended input configuration meets the signal source requirements compared to differential alternatives.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD977 family of 16-bit ADCs from Analog Devices. The 'A' designation typically denotes the higher speed 200 kSPS version, while 'C' specifies the commercial temperature range. The 'NZ' suffix confirms lead-free construction and compliance with current environmental directives.

Analog To Digital Converters (ADC) Replacement Considerations

The AD977ACN serves as the non-compliant predecessor. For direct pin-compatible upgrades, verify if the AD977ACNR (tape and reel) meets packaging needs. Cross-reference with AD977A variants for speed compatibility.
