AD976AARSZ

Analog To Digital Converters (ADC) Overview

The AD976AARSZ is a high-speed, low-power 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 5 V supply and features a successive approximation register (SAR) architecture with a throughput rate of 200 kSPS. The device includes an internal 2.5 V reference and accepts a ±10 V analog full-scale input range. It utilizes a high-speed parallel interface and is housed in a 28-lead SOIC package. Key electrical specifications include a maximum power dissipation of 100 mW, an integral nonlinearity (INL) of ±3 LSB, and a differential nonlinearity (DNL) of -2 LSB/3 LSB. The operational temperature range extends from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Single 5 V supply operation for simplified power management
• Internal 2.5 V voltage reference eliminates external component requirements
• High-speed parallel interface supports rapid data transfer
• Factory calibrated linearity minimizes error correction needs

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise signal acquisition
• Data acquisition modules for monitoring analog sensor outputs
• Test and measurement equipment utilizing high-resolution sampling

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RSZ' against official Analog Devices documentation to confirm RoHS compliance and lead-free status. Confirm package type matches the 28-lead SOIC specification. Check current lifecycle status as older ADC models may be discontinued or subject to limited availability. Ensure the internal reference configuration meets system design requirements without external buffering.

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-supply environment. Compare against the AD976 model if lower throughput of 100 kSPS is acceptable for cost reduction. Consider the PDIP or SSOP packages if surface mount technology is not feasible. Verify that the ±10 V input range aligns with the source signal amplitude to prevent clipping or saturation during operation.

Analog To Digital Converters (ADC) Part Context

The AD976AARSZ belongs to the AD976 family of BiCMOS A/D converters designed for applications demanding high accuracy and speed. This series integrates the ADC core, reference, and interface logic into a single chip. The 'A' variant denotes the 200 kSPS performance tier, distinguishing it from the slower standard version. It represents a mature technology solution for general-purpose data conversion tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives within the same family include the AD976ANZ and AD976ARZ. Verify that substitute parts maintain the 200 kSPS throughput and 16-bit resolution. Check for any changes in pinout or electrical characteristics before implementation.
