AD977AANZ

Analog To Digital Converters (ADC) Overview

The AD977AANZ is a monolithic 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It features a serial interface and operates on a single 5 V supply, consuming 100 mW of power. The device supports a sampling rate of 200 kS/s with a single-ended voltage input type. Key performance metrics include an SNR of 85 dB, DNL of +/- 2 LSB, INL of +/- 3 LSB, and gain error of +/- 0.5% FSR. It is housed in a 20-pin PDIP package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Monolithic 16-bit SAR architecture for high precision conversion
• Single 5 V supply operation with low power consumption
• Serial interface compatibility for simplified system integration

Analog To Digital Converters (ADC) Applications

• Precision data acquisition systems
• Industrial process control instrumentation
• Medical equipment requiring high-resolution signal digitization

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'AA' against the manufacturer's current datasheet to confirm pinout and electrical specifications match the required design. Ensure the 20-pin DIP package aligns with the PCB footprint. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 200 kS/s speed are sufficient for the application. Compare against the AD977CRZ variant if surface mount packaging is preferred over through-hole DIP. Evaluate the single-ended input requirement against differential input needs of other ADC families.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD977 family of 16-bit SAR ADCs from Analog Devices. It shares architectural similarities with the AD977CRZ but differs in package style. The series is designed for applications balancing resolution with moderate speed requirements.

Analog To Digital Converters (ADC) Replacement Considerations

The AD977CRZ serves as a direct functional alternative with identical electrical characteristics but utilizes an SOIC-20 surface mount package instead of the PDIP-20 form factor.
