AD977AARSZ

Analog To Digital Converters (ADC) Overview

The AD977AARSZ is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It features a single-ended input configuration and operates with a sampling rate of 200 kS/s. The device utilizes a serial interface for data output and requires dual 5 V power supplies for analog and digital sections. Key performance metrics include a signal-to-noise ratio of 85 dB, differential nonlinearity of ±2 LSB, and integral nonlinearity of ±3 LSB. It is housed in a 20-lead SOIC package and supports an operating temperature range from -40°C to +85°C.

• Vibration monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'AR' indicates the RoHS-compliant lead-free variant and commercial/industrial temperature grade. Confirm the package type matches the required PCB footprint. Check current availability status as older ADC models may have limited supply or be subject to last-time-buy notices from the manufacturer.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of high resolution and moderate speed is required. Ensure the system can accommodate the 5 V supply rails. Verify that the serial interface timing meets the processor's clock requirements. Consider the thermal dissipation capabilities of the SOIC package within the enclosed application environment.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD977 family of monolithic 16-bit ADCs. It shares architectural similarities with the AD977AA and AD977CR variants but differs in packaging and temperature rating. The AD977AARSZ specifically denotes the industrial temperature range version in the SOIC-20 package.

Analog To Digital Converters (ADC) Replacement Considerations

The AD977AA is a pin-compatible alternative in a different package. The AD977CR offers similar electrical specifications in a smaller SOIC-20 package. Verify pinout compatibility before substitution.
